Products Detail

Specification of this China Wholesale Ga Pressure Seal Gate Valve

The pressure seal gate valves are designed in accordance with API600 and ASME B16.34 for service of high temperature and high pressure and are widely used in fossil fuel power plant. Compared with bolted bonnet joint valves, it provides absolute reliable sealing of the bonnet joint, so that the pressure seal valves are more compact and rigid as well as maintenance cost-effective at high temperature and high pressure service.

This kind of gate valve is not only characterized as simple structure and reliable usage, but also able to create slight flexible deformation to compensate the deviation of the sealing face angle generated during processing, thus improving the process performance. In addition, at seat and gate disc seal surface are over-lay with iron-base alloy or Co-base alloy or carbide alloy for long duration.

Product advantage of this China Wholesale Ga Pressure Seal Gate Valve
Pressure Seal Gate valve has the following advantages:
1) Pressure Seal Gate valve allows the structure of the valve body, valve cover tight junction structure, the provincial Public Works save cost, safe and reliable.
2) valve pressure in the valve cover seal, the use of the modular structure to achieve linear sealed its seals at the same time the use of austenitic stainless steel, anti-cavitation, extended life, thereby ensuring that the valve seal under high-pressure differential did not leak.
3) valve in the 2500 pounds and above level, the body cavity sealing contact with the surfacing of stainless steel lining Department to avoid the valve sealing region under high-pressure differential erosion by soft drinks appear Ma leakage point, thus to ensure a safety valve, long-term operation.
