Description:
A41H type Closed Spring Loaded Low Lift Type Safety Valve are used for the equipment and pipeline of the petroleum gas, air water etc. medium what the working temperature are less than 300°C.A41Y-P/R type are used for the equipment and pipeline of the quality with corrode medium what the working temperature are less than200°C.Take for extra pressure devices.
Closed Spring Loaded Low Lift Type Safety Valve is mainly used forThe boiler,pressureContainers andThe pipeOn the control pressure shall not exceed the specified value, play an important protective effect on personal safety and equipment operation.Note the relief valve must pass through pressure test to use.Reflux valves install at the liquid reflux pipe of LPG tank pump outlet. When the front pump pressure greater than rated value, safety reflux valve reduce pressure & back flow.

Structure
Safety reflux valve include flange parallel type and right-angle type. Disc sealing material is PTFE, good sealability. Valve open and close function is realized by the inlet and outlet different pressure.
Working principle
When inlet pressure is greater than outlet pressure of 0.5MPa, spring is compressed, and valve open automatically. When inlet pressure is less than outlet pressure of 0.5MPa, the valve get closed automatically by spring moving.
