Back To List  

PSB gate valve with bypass。pressure bonnet valves。

Pressure Seal Gate Valve
Features
1. Self-sealing high-pressure 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.
