Anderson Greenwood 200/400/500/700/800 Series Pilot Operated Pressure Relief Valves
Superior performance and advanced overpressure protection technology
Features
Soft seat design: provides repeatable airtight performance before and after the pressure relief cycle.
Metal-to-metal seat design: Guarantees pilot valve performance in high temperature applications.
Gas-tight valve seat close to the set pressure: allows higher system operating pressures and therefore achieves maximum process output; insensitive to vibration applications; reduced product loss.
Pop-up action available: No main valve throttling helps prevent freezing problems in low temperature or refrigerant applications.
Adjustable actions are available: minimize product loss at each pressure release; reduce environmental pollution; avoid oversize consequences; not as sensitive to inlet pressure loss as prominent actions.
Field test connection: Quickly and easily verify set pressure while the valve is in use.
Balanced design: lift is not affected by back pressure; no need for expensive and fragile bellows to balance high back pressure.
Full lift at set pressure: no overpressure is required for full lift; D.O.T. is allowed to be set higher than MAOP (maximum allowable operating pressure) when using a protruding action.
Replaceable soft seats and seals: All seats and seals can be easily and quickly updated; no expensive and time-consuming seat grinding is required.
