Relief Valve cracking pressure from 50psi to 6000psi, for liquid or gas service, materal ss316, various end connections
Valves open when system pressure reaches the set pressure. Then the medium flow out to release system pressure. Valves close when the system pressure is lower than the set presure.
The opening height and the system pressure are direct proportional. However, there's no limit for relieving capacity. So valves in this series should be selected carefully according to system requirements.
