Product Features

» Split-Body Design: Machined inner body prevents media adhesion in the body cavity.
» Full Port Design: Minimizes pressure drop and maximizes flow capacity.
» Leak-Proof Packing: Packing at both the top and bottom eliminates leakage to the surrounding.
» Through Gate with O-Port: The gate cuts through the media when closing and returns it when opening, with increased thickness for higher pressure.
» Polished Gate Surface: Both sides are polished for a tight seal and reduced jamming.
» Hard Chrome Coated Gate: Ensures metal sealing for 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.
» Bidirectional Flow Handling: Seats on both sides allow the valve to handle flow in both directions equally.
» Stem Cover: Ensures a long service life for the stem.
» Minimized Torque: Two thrust bearings reduce operating torque.
» Grease Nipple: Provides lubrication for bearings to enhance performance and longevity.
