Paralle Single Wedge Gate Valve

• Z643 series
• Flanged end
• Single wedge gate
• 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.
