Introduction video of forged Gate Valve :
Forged Gatevalves are great for high-temperature, high-pressure applications, they cannot be made in all kinds of shapes and sizes.GZP Forged valves including forged-steel gate, globe, and check valves and forged ball valves which are widely applied in boiler, petroleum, chemical, metallurgy, energy systems and critical power-industry applications
The range of GZP Forged steel valves design is as follows:
1.Size: 1/2” to 2” DN15 to DN1200
2.Pressure: Class 800lb to 2500lb PN100-PN420
3.Connection ends: Socket weld end to ASME B16.1
Screwed end (NPT,BS[) to ANSI/ASME B 1.20.1
Butt weld end (BW) to ASME B 16.25
Flanged end (RF, FF, RTJ) to ASME B 16.5
4.Temperature: -29℃ to 485 ℃
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.
