Gresswell

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.

Sizes Available: 

DN15 - DN80 (½” – 3”)
