High Pressure Seal Gate Valves

The design and manufacture of high-pressure valve is in accordance with ANSI B16.34, the High Pressure Seal Gate Valves has a beautiful shape, compact structure, reliable sealing. Valve for the Class 900lb-Class4500lb various tubes on the road.
High-pressure self-sealing valve has the following advantages:
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.
