Paralle Double Wedge Gate Valve

Double Wedge Gate Valve

DN:1/2″to 28″

Connect:Flanged

Metal Seat:-40~550℃

Tightness:As per API598

Operation:Pneumatic Actuator

Description

• The flexible gate design provides reliable sealing and prevents the stucking problem caused by gate distortion under high working temperature.
• Single gate with constant closed contact between gate and seat.
• It is with back seat design to avoid medium contact with packing and provide in line packing replacement.
• Low flow resistance and low operation torque and bidirectional tightness.
• The erosion that sealing face suffered is much lower than globe valve .The construction is also very compact.
