Introduction video of  Gate Valve :   

Gate valves are characterized by a traveling wedge, which is moved with the operation of the stem nut. The wedge travels perpendicular to the direction of the flow.
Gate valves are double sealing design, it usually have a minimum pressure drop when fully open, provide tight shut-off when fully closed.

The range of GZP gate valve design is as follows:
1.    Size: 2” to 48”   DN50 to DN1200      
2.    Pressure: Class 150lb to 2500lb  PN10-PN420    
3.    Connection ends: ASME B 16.5 in raised face(RF), Flat face(FF) and Ring Type Joint (RTJ)
ASME B 16.25 in butt welding ends.
4.    Face to face dimensions: conform to ASME B 16.10.
5.    Temperature: -29℃ to 425 ℃
GZP valves can be manufactured in all kinds of materials to meet different requirements from clients, especially in NACE standard.
GZP valves can be equipped with gear operator, pneumatic actuators, Hydraulic actuators, Electric actuators,bypasses,locking devices,chainwheels,extended stems and many others are available to meet the customers’ requirements.
