Gresswell Valves G36 General Purpose Pressure Relief Valves
In order to prevent a safe pressure being exceeded in pressurised systems, Gresswell Valves have produced the G36.
The lift is proportional to the system overpressure. The G36 is particularly suitable for most liquid applications where a small discharge often prevents the safe pressure in a system being exceeded.
The Gresswell G36 is also suitable for steam, gases & vapour applications where a low discharge is suitable.
