Description

Gresswell's G55 Bronze Proportional Lift Pressure Relief Valve is suitable for liquid, steam and gas; used to prevent safe pressure being exceeded in pressurised systems, with the lift being 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 and steam, gas and vapour applications where a low discharge is suitable.

Typical applications include: vented / unvented systems, steam boilers, pump, pipeline and vessel protection.

Gresswell Valves are quality assurance approved to BS EN ISO 9001: 2008 and manufactured in accordance with BS EN ISO 4126-1 & BS6759.
