Description:
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 safety and personnel and equipment can be guaranteed.
Features:
·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 preset pressure value can be adjusted.
Working pressure: 14MPa~ 140MPa (2000psi~20000psi)
Nominal bore: 2’, 3’
Manufacturing standard: API 6A
