Gresswell G55 Bronze Proportional Lift Pressure Relief Valve
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.
Key features:
- Available in sizes: 1/2" to 3" (subject to configuration).
- Temperature range: -10°C to 200°C (Viton) and -10°C to 225°C (Metal and PTFE).
- Pressure range: 0.5 to 20.7 Bar.
- Full Cat IV PED approval.
Gresswell Valves are quality assurance approved to BS EN ISO 9001: 2008 and manufactured in accordance with BS EN ISO 4126-1 & BS6759.
