Crosby Pressure Relief Valves

A market leader in direct spring PRV technology, Crosby was the first to certify on liquid service and one of only a few in the ASME I and III markets. 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 and gas production, refining, petrochemical, and chemical processing systems. They are also used for utility and industrial steam generators, and steam systems in power generation facilities.
