Applications and features:

Low temperature safety valve is widely used in a variety of pressure piping systems, from the security protection. I produced the low-temperature safety valve low temperature sealing performance, stable performance, open sensitive to ensure the safe operation of low-temperature equipment. If the use of toxic, explosive, should use the structure with a bellows.

 

Use and maintenance precautions:

1, the installation should pay attention to the media flow;

2, installation orientation: vertical installation;

3, before installation should pay attention to ensure that the pipeline blowing clean;

4, the valve degreasing treatment, storage, installation should pay attention to keep clean;

5, after the completion of pipeline construction, the pipeline should be all open the valve, repeated thoroughly blown away the pipe residue to ensure that the pipeline system clean no debris;

6, found the valve flap, seat, stem and other precision parts of the wear or damage, the need for timely repair or replacement;

7, safety valve at least once a year check.

 

Note: When installed on the oxygen pipe, avoid oil.
