Flexible Wedge for improved seating and ease of operation, especially in high temperature service. Wedges are accurately guided thru the entire stroke.
Seat faces lapped for smooth finish and superior sealing.
Stems are non-rotating with surface finish to maximize packing seal for low fugitive emissions.
Bonnet and Yoke arms designed for ease of gear, motor or cylinder actuator adaptation.
Each valve is shell, seat and backseat pressure tested per industry standard API 598.
Gland is two piece gland / gland flange design for optimal alignment and uniform packing compression.

Design Features
Design standard: API 602.
Small flow resistance for fluid
Only a small force is required for opening/closing.
No limitation on the flowing direction of the medium
During opening and closing process, the friction between the disc wedge and the seat is small, so the sealing is reliable ensuring tightness and long service life.
The valve is designed in a back-seat structure.
The valve stem sealing is realized by the collaboration of flexible and woven graphite. ensuring a more reliable tightness.
Optional pressure seal bonnet type.
Optional solid-wedge type.
Optional non-rising stem structures.
