PTFE Seated Knife Gate Valve, A351 CF8M, DN50, PN10, 2 Inch

Product Name: PTFE Seated Through Conduit Knife Gate Valve
Body Material: ASTM A351 CF8M
Seat Material: PTFE
Size: DN50, 2 Inch
Pressure: PN10, Class 150 LB
End Connection: Wafer
Operation: Manual

The through-conduit knife gate valve is a bi-directional wafer-type valve, specifically designed for handling highly concentrated flow media. It features a through-going O-port plate, ensuring stable and safe shut-off performance while preventing clogging. The double-seat design allows the valve to manage flow in both directions, offering reliable performance in various applications.

Product Features

» Split-Body Design: Features a machined inner body that prevents media adhesion in the body cavity, enhancing reliability.
» Full Port Design: Minimizes pressure drop and maximizes flow capacity for improved efficiency.
» Leak-Proof Packing: Packing at both the top and bottom ensures no leakage to the surrounding environment.
» Through Gate with O-Port: The gate cuts through the media when closing and returns it when opening. Gate thickness can be increased to accommodate higher pressures.
» Polished Gate Surface: Both sides of the gate are polished for a tight seal and reduced jamming.
» Hard Chrome Coated Gate: Provides metal sealing for enhanced durability and performance.
» Replaceable Side-Entry Seat: Reduces maintenance costs by allowing easy seat replacement.
» L-Shape Seat Retainer: Locks the seat into the valve body and prevents direct flow flushing, providing added protection.
» Bidirectional Flow: With seats on both sides, the valve can handle flow in both directions equally.
» Stem Cover: Extends the service life of the stem by providing additional protection.
» Two Thrust Bearings: Minimize torque for easier operation.
» Grease Nipple: Provides lubrication for bearings, ensuring smooth operation and extended life.
