(1) metal to metal Seat
The blade stops the flow of fluid by the pressure of flowing fluid making blade contact seat. Applicate: Coal fired thermal power plant
Petrochemical industry
Paper industry and Cement industry Pressure: suitable for low pressure less than 10 bar g (up to 30 bar g) Size: 2” ~ 40”
(2) PTFE Seat
Improved sealing performance and chemical resistance more than metal seat type Knife gate valve. It has similar structure to metal seat type valve. Applicate: Petrochemical industry Pressure: suitable for low pressure less than 10 bar g (up to 30 bar g) Size: 2” ~ 40”
(3) Rubber Cushion Seat
Improved the sealing efficiency more than metal seat Knife gate valve which is allowed to leak. Guarantees bi-directionally no leakage and rubber seat blocks the flow of the fluid. Rubber material: EPDM NBR Silicon Application: Ash handling system Desulfurization facility Slurry line Pressure: suitable for low pressure less than 10 bar g (up to 30 bar g) Size: 2” ~ 40”
