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.

Crosby pressure relief valves have maintained leadership in overpressure protection for over 140 years. The direct spring-operated safety and pressure relief valves are among the world’s most widely used for oil and gas production and refining, petrochemical and chemical processing, and conventional and nuclear power. Crosby pressure relief valves maintain the industry’s most extensive and capable flow facilities for testing in air, steam, and water.

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.

Anderson Greenwood Crosby is a US manufacturing company that produces valves for industrial processes, including pressure relief and tank protection valves. The firm was established as Anderson Greenwood in 1947 in Houston, Texas by Marvin Greenwood, Ben Anderson, and Lomis Slaughter Jr to produce a light aircraft, the AG-14. This project never made it past the prototyping stage, but involvement in a missile project soon thereafter saw the firm focus on valve design. In the 1970s, the firm owned the Bellanca name for a while, and during this time attempted to market a new light plane design as the Bellanca Aries, but was short lived with only 4 being sold.

It was purchased in 1986 by Keystone International, in turn acquired by Tyco Flow Control in 1997, with Anderson Greenwood being maintained as a subsidiary. It was subsequently merged with Crosby, another Tyco acquisition.

Anderson Greenwood Crosbyr its acquisition of New England-based Crosby Valve Co., Anderson Greenwood has relocated production, and built a modernized plant, in Stafford, TX, its headquarters. The new capacity is dedicated primarily to the Crosby Style JOS pressure-relief valve line (see Fig. 1), said to be the most popular model on the market today.

According to Chris Fadden, a company spokesman, (AGCO) has not only invested in new production, but has also updated the valve design, and is now providing an enhanced customer-service capability. The JOS-E (for "enhanced") valve, in particular, can now handle higher processing severities than preceding models. The production facility has new machining tools (fig. 2), new quality and inventory-control systems, and expedited delivery capability. AGCO had previously unveiled the "Pronto PRV" hot-line service; customers can simply dial 1-877 333 AGCO (2426) to place orders, check order status, and get follow-up service.

The JOS-E (along with other styles, JBS-E and JLT-E) valves provide overpressure protection in air, gas, steam, vapor and liquid service in the process, refining, and power industries. They are available with flat metal-to-metal seats or soft seats for optimum tightness and minimal maintenance.

Together, Anderson Greenwood and Crosby represent 125 years of valve development; Crosby was founded in 1874 to supply the power industry, and Anderson Greenwood in 1947 as an aircraft component supplier. It claims to have the largest range of PRV offerings that meet ASME Section VIII standards. AGCO is a division of Tyco International.

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