KNIFE GATE VALVE
Metal To Rubber Cushion
RD

Feature

This valve improved the sealing efficiency rather than metal seat knife gate valve which is allowed to leak. It guarantees bi-directionally non leakage and rubber seat blocks the flow of the fluid. Viton, EPDM, NBR or Silicon as rubber material, depending on fluid features.

Application

It can applied to powdered coal conveying pipe, desulfurization facility, ash treatment facility(suitable for pipe transporting powder) in power plant. Also it can be applicable to ash slurry line thanks to superior sealing performance.

 
METAL SEAT
 

Feature

Metal to Metal Seat type Knife Gate Valve is called Stainless Steel Bonnetless type Knife Gate Valve and MSS-SP-81 Code is applied to it. This valve is mostly used for the pipes which transport fluid and has features that the blade stops the flow of fluid by the pressure of flowing fluid making blade contact seat.

Application

For example, this is usually used for the pipes which transport powdered coal (desulfurizing equipment and dust collector) in power plant, petrochemical industry, Paper industry and Cement industry.

P.T.F.E. Seat
 

Feature

P.T.F.E seat type improved sealing performance and chemical durability rather than metal seat type knife gate valve. It has similar structure and sealing direction to metal seat type valve. This valve is suitable to the line of petrochemical products with high durability.

Application

This valve can be applied to finished petrochemical products pipe or the pipe which required better sealing performance than Metal seat.
