Spring-loaded body
pressure relief valve with
bursting disc (UGSV)
The body pressure relief valve with bursting disc is supplied fully assembled, i.e.
equipped with the bursting disc.
Non-spring-loaded design

Always operate the UGSVA variant in combination with a lockable globe valve. Never
replace the bursting disc during operation. To do so, the pressure in the gate valve
must have been released.
