Liquid Safety Valves and Hydraulic Surge
Liquid Safety Valves and Hydraulic Surge
(OP)
Most everyone is familiar with safety valve chatter due to excessive friction losses in inlet pipe.
But given a liquid filled system with long piping and the pressure source liquid near (but below) safety valve set,
Is it possible to have repeated activation due to hydraulic surge (not friction loss)??

Hydraulic surge is definitely detrimental for conventional PSV's, that is the reason there are specific PSV's in the market for this purpose:"Surge pressure safety valves".
However we don't name the issue of hydraulic surge on PSV's as "chattering".
Hope this help
