Through conduit gate valves are an alternative to ball valves for transmission pipelines. The choice is very often based on past customer satisfaction, more than any technical consideration. FLUITEK ORSENIGO VALVES through conduit valves feature standard principles of this well known type of product. The disc is of slab type gate, seat rings are floating, energized by means of multiple springs, and the line fluid pressure pushes the upstream ring against the disc, thus assuring the sealing. The system allows the so called “self relieving” effect, i.e. any over-pressure acting in the body cavity is discharged in the line when force caused by the over-pressure on the seats exceeds the force provided by the springs. At the same time, the construction permits the double block and bleed functioning meaning that pressure applied contemporaneously upstream and downstream pushes both seats against the disc and opening the body cavity bleed relieves any pressure and fluid in the body cavity.Get more news about through conduit gate valve,you can vist our website!

Standard construction is based on cast body, disc from plate or forging and all parts, particularly body cavity and disc, are precisely machined to control with high accuracy the parallelism and orthogonality of the parts. Two basic sealing systems are provided: soft seating and metal-to-metal seating. The first for gas and clean liquids service, the second for fluids containing solids or otherwise abrasive components. The soft seated construction is normally provided with secondary sealing system, i.e. with the ability of injecting a highly dense fluid (grease) into the seating area to help sealing mechanism in case of damage of the soft inserts.

A variety of materials are available: carbon steel, low temperature carbon steel, austenitic stainless steel, duplex and superduplex stainless steel and nickel alloys. Compliance with NACE MR-01-75 and NACE MR-01-03 is provided. Soft seated valves are provided with reinforced PTFE or Nylon inserts, depending on specific service and pressure class. Coatings include electroless nickel plating, nickel alloy overlays of seat pockets, tungsten carbide coating for metal-to-metal seated valves.

Standard of reference is API 6D full bore. Flanged and BW ends available. Construction with extension pups is also available, upon customer request. Stem sealing alternatives: o-rings, adjustable packing system, enclosed packing system with Chevron-type rings and lantern ring with grease injection fitting. Very often this type of valve is used in underground service and proper stem extensions are provided. Testing is per standard requirements, or per any supplementary test request by customers.

Feds Issue Guidance Around Ebike Use on Forest Service Lands

The US Department of Agriculture’s Forest Service has finalized new guidance on how ebike use will be managed in national forests and grasslands.To get more news about rad rover 5, you can visit official website.

“The updated guidance clarifies existing policy and provides guidelines to local Forest Service employees that may be considering expanding ebike access at site-specific locations,” the Forest Service stated.

The agency currently allows ebikes on all Forest Service roads already open to motorized vehicles, as well on 60,000 miles of so-called “motorized” trails—representing 38 percent of all trails under the Forest Service’s management.To get more news about waterproof bag for bike, you can visit official website.

In addition to confirming that ebikes can continue to operate on currently authorized roads and trails, the finalized guidance “lays out a process to evaluate future requests for expanded access,” the Forest Service stated. “The updated guidance also outlines the required environmental analysis and public input required before making future decisions to expand local e-bike access.”In a news release, Forest Service chief Randy Moore said, “National forests and grasslands are a place for all people to recreate, relax, and refresh. The additional guidance will help our district rangers and forest supervisors better serve their communities with a policy that allows managers to make locally based decisions to address ebike use.To get more news about tektro aries, you can visit official website.
Advocacy group the International Mountain Bicycling Association sees the new guidance as a mixed bag, at best, on expanding access for electric mountain bikes, or eMTBs, on lands under the Forest Service’s jurisdiction.

In a statement on the association’s website, IMBA director of government affairs Todd Keller wrote, “The final rule has some great elements: It requires a local public process to adequately collect local sentiment on possible pros and cons of eMTB access…; it distinguishes between Class 1, Class 2, and Class 3 eMTBs to ensure quality experiences for all trail users; and it manages eMTBs as a new category, separate from traditional mountain bikes. These steps are all in line with IMBA’s recommendations.
However,” Keller continued, “the final rule does not create an exclusion for eMTBs (as nonmotorized vehicles). Therefore, the directives would reclassify nonmotorized trails as motorized trails to allow eMTB access. This will create funding complications, lead to increased user conflicts, and fundamentally change nonmotorized trail allocations across the forest system.”

The Forest Service manages nearly 160,000 miles of trails in 42 states and Puerto Rico for a variety of recreational activities, including mountain biking, horseback riding, snowmobiling, cross-country skiing, hiking, and backpacking.

The US Department of the Interior’s Bureau of Land Management and National Park Service, two other key federal land management agencies, allow ebike use on 18,000 miles and 16,000 miles of trails, respectively.

Electric bikes soon to be humming along national park trails

Motorized electric bicycles may soon be humming along serene trails in national parks and other public lands nationwide. It’s part of a new Trump administration order — hotly opposed by many outdoors groups — that will allow e-bikes on every federal trail where a regular bike can go.To get more news about electric mountain bike, you can visit official website.

Sales of the bikes, powered by both pedals and battery-driven small motors, are booming, and some aging or less fit people have sought the rule change. It will allow them to whirr up and down biking trails in the country’s roughly 400 national parks and other federally managed backcountry areas.Interior Secretary David Bernhardt signed the order without fanfare Thursday, classifying e-bikes as non-motorized bikes.

The e-bikes “make bicycle travel easier and more efficient, and they provide an option for people who want to ride a bicycle but might not otherwise do so because of physical fitness, age, disability or convenience,” National Park Service Deputy Director P. Daniel Smith said in a statement Friday.To get more news about electric bike, you can visit official website.

Welcoming the change in Bar Harbor, Maine, on Friday, Gordon Goodwin, 69, said he and his wife look forward to riding the 57 miles (92 kilometers) of carriage paths that meander throughout Acadia National Park.

The paths, offering stunning views of lakes, mountains, forests and the ocean, are popular with bicyclists, but e-bikes have had to stay on the park’s roads instead.To get more news about Fat Tire Electric Bikes, you can visit official website.

“We’re stoked. We’re really stoked,” Goodwin said. “There’s just too much traffic on the main park roads that you can’t enjoy them. It’ll be great to get in the park and see nature and all that stuff.”

But more than 50 hiking, horse-riding and other outdoor and conservation associations, including the Appalachian Trail Conservancy and Pacific Crest Trail Association, objected in a July letter to the Interior Department. They say the administration is fundamentally changing the nature of national parks with little or no public notice or study.

“If you’re hiking on a trail in Utah and you’re rounding a bend and something’s coming at you at 20 mph, that really changes the experience,” said Kristen Brengel, a vice president of the National Parks Conservation Association, a nonprofit that advocates for the national park system.

“It’s pretty jarring” to those who take to public lands to escape city noise and stress for nature, Brengel said. “You’re adding significant speed and a throttle to those trails.”E-bikes are the fastest-growing segment of the bicycle industry, with U.S. sales jumping 72% to $144 million last year, according to the NPD Group, which tracks bike sales. The motorized bikes are popular with commuters and aging baby boomers who might not otherwise get out on a bicycle.

The bikes, which can cost $2,000 or more, combine the frame of a regular bike with lightweight batteries and electric motors.

In parks and other public lands as on city streets and sidewalks, people moving on vehicles powered by electric or gasoline engines frequently jostle for the right of way with people on foot or traditional bikes. In the National Park Service, officials over the decades have tried to carefully sort out rules and systems to minimize conflicts.

In their letter, the outdoor groups complained the decision to allow motorized bikes on bike trails breaks with policies dating back to the early 1970s confining cars, dirt bikes, all-terrain vehicles and all other motorized vehicles to roads and designated areas or trails on public lands.

Specialized Seeing Exponential Growth As Mountain Bikers Turn To E-Bikes

Mountain biking is exploding. Trail usage is surging, and mountain bike sales are jumping. But no one area may be seeing more growth than in the fast-moving world of electric mountain bikes. To get more news about ebike accessories, you can visit official website.

“The bike is having a well-deserved moment right now,” says Ian Kenny, Specialized global marketing leader and former program manager for TeslaTSLA +6.2%. “The growth in e-bikes is even accelerating at a faster pace. The e-bike is on this exponential curve.” To get more news about rad rover 5, you can visit official website.

As the pandemic drew people outdoors for recreation, cycling across all areas saw a massive boost. In more recent months, according to data from NPD Group, higher-end bikes have enjoyed the biggest bump, largely from people already involved in mountain biking looking to upgrade. No area, though, is seeing a surge as that of e-bikes, including electric mountain bikes, with over 200 percent increases in sales figures this year compared to last year. And over 25 percent of all money spent on mountain bikes in 2020 have been of the e-bike variety. To get more news about waterproof bag for bike, you can visit official website.
Specialized, one of the “big three” in the mountain biking world, was one of the first to introduce e-bikes to the mountain lineup, combining engineering offices in California and Switzerland to continue to create. “If you like riding a bike, you are probably going to really like riding an e-bike,” Kenny says. “It lets you do more of the kind of riding you love to do.” In mountain biking, the e-bike comes as pedal-assist, doubling — or quadrupling — pedal power as you pedal up a hill, allowing riders the time and stamina to ride more trails or go farther. The e-bike also opens up the opportunity to ride to trails farther away.
The e-bike doesn’t take the effort out of the adventure, though, in part pedal-assist design and part the nature of e-bikes. “On average, people who ride an e-bike are getting more exercise,” Kenny says, “they are riding more often and farther. For new riders, e-bikes have this incredible effect of leaving you with a positive impression of your ride right away. That learning curve and fitness curve is steep and harsh (in mountain biking). You can go drop a bunch of money and get kicked on your first ride and not be so inclined to get back on. With the e-bike you are much more likely to get back on the next day. For those reasons, we are seeing explosive growth across e-bike categories, especially on the mountain side.”

While Specialized started in e-bikes about a decade ago in the commuter space — still the most popular segment of e-bike creation with multiple new companies coming on board every year — the move to mountain was a natural step for a company mass producing mountain bikes (the Stumpjumper is one of the oldest, longest-standing mountain bike models in the world). Specialized, then, applied learning from early e-bikes and worked to build mountain bike-specific options to give cyclists the power to ride more trails.

Creating an electric mountain bike version wasn’t just about slapping some heavy-duty components on a commuter, though. It comes as a different make entirely. Specialized has focused on building a mountain bike-specific geometry with a lightweight system and a bike that “rides and feels much more like a bike and almost identical to a bike without a motor or assistance.”

Turbo Levo, consistently one of the highest-rated electric mountain bikes on the market, originally launched in 2015 and has seen multiple iterations, refining the system to improve integration and stress mitigation. Specialized now has a range of Turbo electric mountain bikes to offer differing varieties based on trails, such as the Levo with more power or the Levo SL with a more lightweight, nimble feeling. The bikes still fit within mountain expectations, such as 150mm of travel, and the Levo SL comes in at 38 pounds, the lightest in its class and 240 watts of rider amplification that translates to an assist up to 20 miles per hour while personalizing the power delivery. The Turbo Levo and Turbo Kenevo versions come with 565 watts of power.

Specialized has done this in-house — many companies outsource the e-bike componentry — so they can have control over every step of the process, including hardware and software. “It is what allows us to bring bikes to riders that they can’t find elsewhere,” Kenny says. “It is really the difference between taking parts and components off the shelf and fitting them together versus creating this experience that is fluid and smooth and consistent. It is a complex machine that takes a lot of engineering and work to create an experience that looks great and when you get on it you feel the difference.”

The evolution of the software has proven instrumental in the growth of the Turbo electric mountain line. With the goal of creating a smooth assistance that doesn’t surge power, Specialized mined data from millions of miles of trails ridden on its bikes to refine the software. But they’ve also streamlined the hardware. Specialized has tuned the battery power, based on data, to offer just what riders need so they can strip weight and refine the feeling, encasing it in a true mountain bike design for trail punishment.

Harley-Davidson’s Serial 1 announces a limited-edition electric mountain bike

Serial 1, the e-bike company spun out of Harley-Davidson nearly two years ago, unveiled another premium model designed to make you open your wallet in helpless surrender. The Bash/Mtn is the company’s first electric mountain bike, and from the look of it, it can absolutely destroy an off-road trail.To get more news about ebike for sale, you can visit official website.

A rigid, single-speed eMTB (electric mountain bike), the Bash/Mtn is designed for serious off-roading, while also promising to require less maintenance thanks to its simplified design. But it won’t be cheap, with a suggested retail price of $3,999.To get more news about electric mountain bike, you can visit official website.

“No fussy suspension to tune, no finicky drivetrain to adjust — just two wheels, one gear, and one purpose, to provide the most direct connection between you and the trail,” the company says.The Bash/Mtn design was based on a Serial 1 engineer’s personal build and adapted on the company’s entry-level Mosh/Cty model. This new premium model keeps many of the Mosh/Cty features, including a Gates Carbon Drive belt, Brose S Mag mid-drive motor, TRP hydraulic disc brakes, internally routed cables and wires, and integrated LED lighting.To get more news about electric bike, you can visit official website.

It departs from the Mosh/Cty with the inclusion of grippy Michelin E-Wild knobby tires and a “spine-saving, shock-absorbing” SR Suntour NCX suspension seat post. The Yucca Tan paint with special Gloss Graffiti graphics also differentiate the Bash/Mtn from Serial 1’s other models. And thanks to a new deal with Google, the Serial 1 app will relay all the ride data and other metrics for users to pour over.Serial 1’s eMTB features an integrated, removable 529Wh battery that should power the bike for 30–95 miles, depending on the ride mode. It’s a throttle-less Class 1 e-bike, meaning it tops out at 20mph. Serial 1 didn’t provide the power rating, but with 90 Newton-meters and 66 foot-pounds of torque, it’s sure to get you up a steep slope without much effort.

Much like the gorgeous, vintage-inspired S1 Mosh/Tribute, the Bash/Mtn will have a limited production run. Only 1,050 units will be produced: 525 for the United States and 525 for Europe.

Last year, the company announced a series of exclusive, one-of-a-kind e-bikes that it was auctioning off under its 1-OFF series brand name, with the Schwinn Sting-Ray-inspired Mosh/Chopper as the first offering. (The winning bid was $14,200, which... wow.) At the time, the company said that, much like in the motorcycle world, customization and personalization would play a big role in how Serial 1 thinks about the types of e-bikes it designs.

Flexographic, Gravure and Sheet Fed Offset Printing

Flexography (Flexo) printing uses a raised-image printing plate. Photopolymer, or rubber, plates are used to transfer the print image. Conventional liquid or sheet photopolymer plates are used for line art. Laser-imaged, direct-to-plates (DTP) are used for all four-color process, all duotone, and most halftone images. As the plate cylinder rotates, it comes in contact with an anilox, or ink roller, which inks the raised portion of the printing plate. The plate then transfers the ink to the web, or paper. The anilox roll is laser-engraved with thousands of recessed cells that fill up with ink. The doctor blade controls the ink transfer to the plate. The doctor blade wipes off all ink except what is in the cells of the anilox roll. Compared to offset printing, this method offers significantly more ink transfer. (Refer to diagram below)Get more news about Flexographic Flat Printer,you can vist our website!

There is "gain," or growth, of Flexo images. For example, if the image area is a process/halftone with a 2% dot in the art/plate (typically the minimum for Flexo), it will print between 9-12% dot on coated papers and 12-15% dot on uncoated papers. This gain occurs for several reasons: As mentioned, the amount of ink transferred increases the image dot size. The contact pressure to transfer from anilox to plate to paper also increases the image dot size.

The substrates needed to ensure efficient machineability of roll paper into bags are not as smooth as those in offset printing. A rougher sheet can increase the size of the image dot because it requires more plate pressure to print. In addition, more ink is absorbed in a rougher paper. There also is more inherent machine movement in Flexo than in offset printing, so registration is not as tight and larger traps between colors are required.

Flexo can maintain resolution levels of 65-110 line on uncoated papers (such as Kraft and white) and 110-133 line on coated papers (claycoat).Gravure prints from a "cut-in," or recessed, surface. An engraved metal printing cylinder is used to transfer the printed image to the paper. As the gravure image cylinder rotates in the ink pan, the engraved cells of the image are filled with ink. The doctor blade controls and meters the ink by wiping the excess from cylinder surface, leaving ink only within engraved cells. The gravure cylinder then comes in contact with the paper substrate, transferring the printed image with the help of the rubber impression cylinder, which pulls the ink from the engraved cells. (Refer to the diagram below.)

There is "gain," or growth, in gravure printing. For example, if the image area is a process/halftone with a 3% dot in the art/cylinder (typically the minimum for gravure), it will print between 5-7% dot. Gravure is excellent for printing strong metallic inks.

Gravure prints on rolls of the same claycoat paper as Flexo and therefore has many of the same characteristics. However, gravure offers tighter registration that requires minimal traps and can maintain resolution levels of 150-175 line.
