Safety valves provide safety protection in the system. When the system pressure exceeds the specified value, the safety valve is opened, and a part of the gas/fluid in the system is discharged into the atmosphere/pipe, so that the system pressure does not exceed the allowable value, thereby ensuring that the system does not cause an accident due to excessive pressure.


The installation notes

1. All safety valves should be installed vertically.

2. There should be no resistance at the exit of the safety valve to avoid pressure.

3. The safety valve should be specially tested before installation and checked for tightness.

4. Regular inspection of the safety valve in use.


The common faults of safety valves in application:

When the safety valve is used normally and verified, it may cause various failures due to improper design, manufacture or use. These faults are not eliminated in time, which will affect the safety valve's efficacy and service life. In severe cases, it will endanger the safety of users.

Safety valve leakage problem.


Exceeding the allowable degree of leakage at the sealing surface of the valve disc and the seat, the cause and solution:

a. Leakage occurs because there is a dirt between the valve flap and the sealing surface of the valve seat. It is possible to flush the valve several times.

b. Damage to the sealing surface can be repaired by grinding or grinding after grinding according to the degree of damage.

c. The valve stem is bent and tilted. Should be reassembled or replaced
