API 6A valve Hydraulic Choke Valve
Emergency release valves(safety valve),with self-reset
function, can automatically release pressure when the actual
pressure exceed the preset value. Its release mechanism is of
spring-loaded ball and seat, to protect personnel and high pressure
system.
The value of pressure release can be adjusted from 14Mpa
to 140Mpa through a top adjustment bolt. The valves can be
installed on high pressure fluid control lines, reciprocal plunger
pumps or pressure vessels with maximum working pressure of
105MPa or 140MPa.When the system pressure exceeds the preset
value,it can open the valve;after it drops,the valve will
automatically close.Therefore, the safey and personnel and equipment can be guaranteed.
Union connection makes installation and dismounting
convenient.
The automatic open/close of valve is realized through a spring without shutting down the system for protection, with a better
performance than shear type safety valve.
The value ofpressure release can be adjusted.
