G36 Stainless Steel Safety Relief Valve
These valves are commonly used for preventing a safe pressure being exceeded in pressurised systems. The lift is proportional to the system overpressure. Particularly suitable for most liquid applications where a ‘small’ discharge often prevents the safe pressure in a system being exceeded. Also suitable for steam, gases & vapour applications where a low discharge is suitable.
