Pneumatic Actuated Knife Gate Valve, A351 CF8M, DN150, PN10

Key Specifications / Features

The Pneumatic Actuated Knife Gate Valve, featuring a through-conduit design, is built with a stainless steel ASTM A351 CF8M body for superior corrosion resistance. With a PTFE seat, it ensures tight sealing and reliable performance. Sized at DN150 (6 inches) with a Class 150 LB pressure rating and PN10, the valve has wafer ends for easy installation.

The through-conduit knife gate valve is a bi-directional wafer-style valve designed primarily for highly concentrated flow media. Featuring a through-going O-port plate, this valve ensures stable and safe shut-off performance without the risk of clogging. Its double-seat design allows it to handle flow in both directions effectively.

Product Features

» Split-Body Design with Machined Inner Body: Prevents media adhesion in the body cavity for smoother operation.
» Full Port Design: Minimizes pressure drop and maximizes flow capacity.
» Dual Packing: Seals at both the top and bottom to eliminate leakage to the surroundings.
» Through Gate with O-Port: The gate cuts through the media when closing and returns the portion when opening. The gate thickness can be increased for higher pressure applications.
» Polished Gate Surface: Both sides of the gate are well polished for a tight seal and reduced jamming.
» Hard Chrome Coated Gate: Provides metal sealing for durability and improved performance.
» Replaceable Side-Entry Seat: Reduces maintenance costs by allowing easy replacement of the seat.
» L-Shape Seat Retainer: Locks the seat into the valve body and covers the seat side to prevent direct flow flushing. The valve can handle flow in both directions with seats on both sides.
» Stem Cover: Available to ensure the long service life of the stem.
» Two Thrust Bearings: Minimize torque for smoother operation.
» Grease Nipple: Allows for bearing lubrication to extend service life.
