Polyurethane PU Seated Bi Directional Knife Gate Valve

Pneumatic Actuated Polyurethane PU Seated Bi Directional Knife Gate Valve

TEKO Urethane Lined Knife Gate Valves are designed for on-off applications of abrasive slurry and dry abrasive materials. Flanged Urethane Lined Knife Gate Valves are 100% port area and are ideally suited for applications in mining, chemical and food industries. Flanged PU Lined Knife Gate Valves are available in sizes 2-48" (50-1200mm), and grooved end valves are available in sizes 2-12" (50-300mm). Temperature ratings range from -29 to 80º C as standard. The Carbon Steel body is available with a variety of urethane liner compounds suitable for water, oil, food grade, phosphoric acid, and petroleum.

Our PU Lind Knife valves feature a one-piece, cast-in-place bonded liner that provides bi-directional, drip-tight shutoff to either 150 or 250 psi (1030 or 1720 kPa) CWP. Urethane Lined Knife Gate Valves can also provide bi-directional dead-end service to the full pressure rating of the valve. All wetted surfaces are lined with urethane.

The urethane liner is bonded in place to form a continuous liner throughout the entire body, chest, packing chamber and flange face area. The bonding process enhances the mechanical and abrasion resistance properties of the urethane, which creates a robust seat seal in harsh slurry services. The seamless bonded urethane liner extends over the flange face to serve as the valve's flange gasket.

Specifications

Features

• True bi-directional flow and shut-off, allowing it to be installed in either direction.
• Unique one-piece, precision molded high strength polyurethane liner protects the wetted parts, from corrosion and abrasion. It is field replaceable in all sizes, no need to return to factory for repair.
• The liner has integral flange seals eliminating the need for flange gaskets in most cases.
• The liner has integral sealing beads to support and wipe slurry from the gate, minimizing deflection and improving packing life.
• Testing as per MSS SP-81
• Fully rated 316 stainless steel gate, with optional 17-4 ph to provide improved abrasion resistance against the rigors of abrasive applications.
• Full round port and seat design offers low pressure drop across valve and longer service life in abrasive applications.
• Designed to be a repairable asset, lower the cost of ownership.
• Inverted self-aligning gland box allows for easier setup and longer packing life.
• Complies with MSS SP-81 face-to-face dimensions.

Material List

TEKO Industry Co., Limited, established in 2010, is a rapidly growing industry products manufacturer in China. Throughout 8 years of development, we have been now becoming the major valve supply in industries of petroleum, chemical plant, power station, mining, metallurgy, waste water treatment, shipbuilding etc.

Recently our business scope has covered the industry valves and marine valves, including the gate/globe/check valve, butterfly valve, knife gate valve, pinch valves, high performance butterfly valve, strainer and so on. With our experienced workers, we can now workable with big capacity up to 500 tons per month.

Always bearing in mind “quality first”, we operate production strictly following the ISO9001 regulations. In addition, our valves are hydraulic testing according to the requirements of related standards, such as API598. We ensure that all valves delivered are not satisfy the customer’s requirements, but also exceed their expectation. And we TEKOers truly mean it.

We have engineers with more dozens of years of experiences and that benefit us that we can always updated our valve new technology and new design that can fit most severe fluid services. It is so inspiring after we have handled the tough fluid for our customers, no matter how high temperature/pressure, highly abrasive, highly corrosive is. It also, at the same time, drives us to make progress every single day to offer the best service during the next time.

TEKO’s mission: “Nothing will happen, Except Satisfaction”. Our specialty, down-to-earth attitude, and sound services are core value to us and will lead TEKO to a new height. Please contact us and start to enjoy our good products and services.
