The Cash Acme FV(M)X Series combination temperature and pressure relief valves are designed to offer high capacity protection for domestic and commercial water heating devices.The Cash Acme FV(M)X Series is fully automatic, and the valves reseat after either temperature or pressure relief. The FV(M)X Series Valves are diaphragm guided, and they are suitable for installations where codes require complete shut-off. The larger FV(M)X Series Valves are well suited for such commercial applications as restaurants, hospitals, and laundries. Available sizes include 3/4", 1", 1-1/4", 1-1/2" and 2". The FV(M)X Series offers a choice of either male (designated FVMX) or female (designated FVX) inlet connections.

All Cash Acme FV(M)X Series Valves through 1-1/4" have coated thermal elements to protect against corrosion and mineral build-up. The coating also isolates the copper from galvanic action within the heater. The 1-1/2" and 2" sizes are fitted with stainless steel thermal elements.The temperature relief setting is 210°F (99°C). The FV(M)X Series Valves have a standard factory pressure relief setting of 150 psi. Most models are also available with a pressure relief setting in the range of 75 psi to 150 psi. Lead Free* versions of most models are also available.
