Cryogenic Pressure Relief Valve

Cryogenic Pressure Relief Valve Micro Open Safety Valve For LNG Station

Product overview of spring micro-start closed safety valve

The spring micro-open closed safety valve refers to the valve's valve or plunger and other seals are locked by the elastic pressure of the spring.Once the pressure of the pressure vessel is abnormal, the high pressure generated will overcome the spring pressure of the safety valve, so the locking device is topped Open, forming a pressure relief channel to release high pressure.

The spring micro-lift closed safety valve is different from the general full-lift safety valve. It can be automatically closed after pressure relief, without human manual reset. Some of our spring micro-lift closed safety valves are suitable for LPG with operating temperature ≤300℃ , Air, water and other media equipment or pipelines. Some of our stainless steel safety valves are suitable for equipment or pipelines with corrosive media at operating temperatures ≤200°C, as overpressure protection devices.

Main items of safety valve order

Safety valve medium, pressure level, opening method (full start/micro start), set take-off pressure, determine valve size, connection method, standard maximum temperature resistance, release flow rate/hour, valve body material, internal valve body structure, working principle , Installation instructions and other relevant technical data. The main basis for safety valve selection is (the take-off pressure and tidy pressure flow temperature) caliber will be given by the general design institute, and in fact through steam pressure, flow rate and take-off pressure, you can guess the safety valve Size. Generally, it will be one size smaller than the caliber selected by the design institute. When the use occasion is very important or the environment is more complicated, please provide the design drawings and detailed parameters as much as possible. Our company experts will review and check for you.
