Product Features

» Split-Body Design: The machined inner body prevents media adhesion in the body cavity, ensuring smooth operation.
» Full Port Design: This design minimizes pressure drop and maximizes flow capacity.
» Leakage Prevention: Packing at both the top and bottom eliminates leakage to the surrounding environment.
» Through Gate with O-Port Cut: The gate cuts through the media when closing and returns it when opening. The gate thickness can be increased for higher pressure requirements.
» Polished Gate Surface: The gate surface is polished on both sides, providing a tight seal and reducing jamming.
» Hard Chrome Coated Gate: The gate is coated for metal sealing, enhancing durability and sealing performance.
» Replaceable Side-Entry Seat: The seat is replaceable, reducing maintenance costs.
» L-Shape Seat Retainer: This design locks the seat into the valve body and covers the seat side to prevent direct flow flushing, improving reliability.
» Bidirectional Flow Capability: With seats on both sides, the valve can handle flow in both directions equally.
» Stem Cover: Available to ensure the long service life of the stem.
» Two Thrust Bearings: These minimize torque, improving valve operation.
» Grease Nipple: Allows for easy bearing lubrication to maintain smooth function.
