anderson greenwood pressure safety valve manufacturer

Anderson Greenwood pressure relief valves, tank protection products, primary isolation valves, and instrumentation set the industry standard for repeatable service and long service life. The breadth of Anderson Greenwood product offerings for both standard and specialized installations combined with unmatched application expertise, product quality, and availability provides for complete valve solutions in the oil and gas, chemical, power generation, and refining industries.

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.

WPC provides customers with total pressure relief management solutions that support a facility’s entire lifecycle, transforming the way you ensure plant safety. Using Emerson comprehensive range of Pressure Safety Valves and WPC Engineering Services team ensures that the design of your pressure relief system is done correctly to respond to every overpressure scenario.

Since 1874, Crosby direct spring operated safety and relief valves have been among the world’s most widely used relief valves for gas, liquid, steam and multi-phase applications in Oil & Gas production, refining, petrochemical and chemical processing systems as well as for utility and industrial steam generators & steam systems in power generation facilities.

In the highly specialized field of pressure relief devices, no manufacturer can match the diversified products and experience of Emerson comprehensive range of Pilot operated Pressure Safety Valves with brands like Anderson Greenwood and Birkett.

With more designs than any other worldwide manufacturer, Anderson Greenwood’s and Birkett"s product technology solves applications from the most severe problem to very basic service conditions. These designs include a high temperature metal seated pilot valve, premium performance spring operated valves, API 526 flanged conventional and balanced bellows valves and an extensive iron and bronze product range.

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.

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.

Looking for the right pressure relief valve to protect your system? Anderson Greenwood and Crosby are the premier suppliers of both direct spring operated and pilot operated pressure relief valves.
