Premium performance direct spring operated pressure relief valves featuring special internals and soft seats to deliver optimum, accurate performance.

A modulating pilot operated pressure relief valve for economizer applications that meets the stringent requirements of ASME Section I at high temperatures.

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.

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.

Features: Types 81 and 83 are direct spring operated valves designed with special patented internals and soft seats to provide superior performance. This range is capable of solving the most difficult pressure relief problems with valves suitable for gas vapor, and steam service. Type 81 and 83 valves carry the ASME Section VIII Code Stamp.

Features: The Type 81P is a fully back pressure balanced, direct spring operated valve designed specially for liquid service. The valve is fully open at only 10% overpressure and has a pressure-loaded spindle ring to ensure stability with no chatter.

Features: The Series 400 is a no-flow, modulating action POPRV design suitable for gas, liquid and two-phase applications. The Series 400 represents the very best state-of-the-art technology providing safety relief valve performance not possible from direct spring PRV’s.

Features: The Type727 safety valve has been specifically designed to provide a valve with premium seat tightness on high temperature gas and steam service. The 727 has all metal seating surfaces and is ASME Section VIII Code Stamped.

Features: Designed for cryogenic and non-cryogenic storage tanks the Anderson, Greenwood Series 90/9000 POPRVs provide extremely accurate valve setting and ultra sensitive response with set pressure as low as 4″wc (10 mbarg). The Series 9000 is also available as a pilot operated vacuum breaker for highly sensitive and air-tight vacuum service.

Features: The Anderson, Greenwood Safety Selector Valve (SSV) is a unique device, developed to provide a safe and efficient method of switching from an active PRV to a standby PRV. The SSV has less than 3% pressure drop to the active PRV inlet, in accordance with ASME Section VIII Code and API RP520 Part II. The SSV is provided with a ‘foolproof’ locking mechanism. Tandem Safety Selector Valve systems are available which allow positive and simultaneous switching of both inlet and outlet SSV’s while maintaining overpressure protection at all times.

Features: Tank Blanketing provides an inert gas blanket over the liquid in a liquid storage tank. The Anderson, Greenwood Trans-Zero Regulator is a pilot operated, dome-loaded diaphragm type regulator capable of reducing blanketing gas from 14 barg to 12.5 mm wc in a single step providing bubble-tight shut off and low maintenance costs.
