Product Features

» Split-Body Design: The machined inner body prevents media adhesion within the valve cavity, ensuring smooth operation.
» Full Port Design: Minimizes pressure drop and maximizes flow capacity for efficient operation.
» Double Packing: Packing at both the top and bottom eliminates leakage to the surrounding environment, ensuring a tight seal.
» Through Gate with O-Port: The gate cuts through the media with an O-port disc when closing, and the portion is returned when opening. Gate thickness can be increased for higher pressure applications.
» Polished Gate Surface: Both sides of the gate are polished to provide a tight seal and minimize jamming.
» Hard Chrome Coating: The gate is coated for enhanced metal sealing and durability.
» Replaceable Side-Entry Seat: Reduces maintenance costs by allowing easy seat replacement.
» L-Shape Seat Retainer: Locks the seat into the valve body and covers the seat side to prevent direct flow flushing.
» Bi-Directional Flow: With seats on both sides, the valve can handle flow in both directions equally.
» Stem Cover: Available to protect the stem and extend its service life.
» Low Torque Operation: Two thrust bearings are used to minimize torque for easier operation.
» Grease Nipple: For easy lubrication of bearings, ensuring smooth and long-lasting valve performance.
