Back pressure effect on bellows-type safety valves

2017-08-08View Original

Thread Content

I have a question for discussion: Do you know the impact of the back pressure of a bellows-type safety valve on its operating pressure?
Reply #22017-08-08
The back pressure shall not exceed 30 percent of the set pressure; the correction factor affecting drainage is determined by the manufacturer.

The back pressure of the corrugated plate safety valve shouldn’t affect the setting pressure, right? It does affect the discharge rate

It will affect the takeoff pressure, as the bellows will relieve the load.
