Through our “VR” certification from the National Board of Boiler and Pressure Vessel Inspectors, Cornerstone provides “24/7” asset management and repair services for all brands of pressure relief products in ASME Section I and VIII applications and is capable of testing on steam, air/gas, and liquid medias.

Bubble-tight seats near set pressure: Allows higher system operating pressure and, therefore, maximum process output; not as sensitive to vibrational and pulsating service; reduces product loss.

Modulating action available: Minimized product loss per relief situation; reduced environmental pollution; avoids oversizing consequences; not as sensitive to inlet pressure losses as pop action.

Full lift at set pressure: No overpressure required for full lift; allows D.O.T. installation to be set higher than Maximum Allowable Operating Pressure (MAOP) when pop action is used.

High Gain Modulating Action available on 400 Series pilots providing full main valve lift by 5% overpressure while minimizing product loss during relief events.

Minimizes possibility of freeze-up in applications involving a cryogenic or refrigerant and allows for D.O.T. applications to be set higher than Maximum Allowable Operating Pressure.

Type 81P spindle design balanced against the effects of back pressure without the use of a bellows, reducing both initial purchase and associated long-term maintenance costs.

Balanced design ensures proper valve operation and lift unaffected by back pressure; pilot exhausts to main valve outlet with no effect on set pressure.

Anderson Greenwood pilot operated pressure relief valves provide advanced, reliable and efficient overpressure protection. These valves are designed for a wide range of applications, from simple to the most complicated service conditions. A pressure relief valve is a type of safety valve designed to protect equipment and pressure vessels from over-pressurization. It protects the system and keeps the people operating the device safely in an overpressure event or equipment failure.

A pressure relief valve is manufactured to withstand a maximum allowable working pressure (MAWP). When an overpressure event happens, the pressure relief valve detects high pressure beyond its design’s specified capability. The pressure relief valve discharges the extra fluid or gas to flow from an auxiliary passage away from the system.

They’re instrumental in applications, including oil and gas, power generation like central heating systems, and multi-phase applications in refining and chemical processing, where proper pressure levels are essential for correct and safe operation.

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.

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.

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.

If the determined valve type and model are provided by the customer, the customer should correctly explain the meaning and requirements of its model, and sign the contract under the conditions that the supply and demand sides understand and agree.
