Used in

Common applications for CASH ACME
Water heating systems — Cash Acme temperature and pressure relief valves protect storage tanks and boilers from overpressure and excessive temperature.
Potable water distribution — Lead-free hose bibb vacuum breakers such as the 19600-0000LF prevent back-siphonage at hose connections.
Building water supply — Standard capacity water pressure regulators (e.g., 22999-0045) reduce and stabilize incoming pressure to 10–70 psi.
Point-of-use plumbing — Thermostatic mixing valves like the HG110D blend hot and cold water at sinks to maintain safe outlet temperatures.
Piping and tank protection — Vacuum relief valves (22397LF, 22398LF) admit air to prevent vacuum collapse in water and process piping.
Hydronic and steam systems — Cash Acme pressure regulators and relief valves maintain stable operating conditions in heating loops.
