Pneumatic Safety Relief Valve
Pneumatic Safety Relief Valve
(OP)
Hello,
I'm looking to obtain a pneumatic safety relief valve. The specs. are 1/4" inlet 175 psi set pressure (popping pressure) that will be used on a system that is kept at 125 psi under normal operation. The equipment needs to be capable of operating in a temp. range of -40 to 155 F and no leaks up to 150 psi. The current valve we use is a hard seal valve (Stainless Steel ball on Brass), and we are looking to replace this due to minor leaks that were reported and noticed at normal operation. The replacement valve I'm looking for would preferrably be a soft seal, do to less likely to leak. Viton seals do not meet my temp. requirement. Does anyone have any suggestions?
Thanks!

Also Code Case 2211-1 and 2446 for some ideas.
See NBIC Part RE,Appendix D,Appendix E,Appendix F,and Appendix I.
Should find what you need.

Does anyone have any experience with a CDI soft silicon seat model ST25. In particular, how well it performs in very cold (down to -40F) and very warm (up to 155F) environments?
Thanks again, for everyone's input!

Just remember there is most likey particles and dirt in your vessel and I have seen the embed on the seat.
Also a soft seat is likey to take a bit of a set and if the valve lifts....things move.
