Caleffi’s 5350 Series AutoFill fast-fill/pressure-reducing valve maintains system pressure at a set value, automatically feeding water as required when installed on the water inlet piping in closed hydronic systems.
With an energy output up to four times the energy input, it’s easy to understand why geothermal and air-source heat pumps are an increasingly popular choice for hydronic applications.
In 2003, Milwaukee Valve became the first U.S. valve company to offer a bronze valve that met the requirements of NSF 61. Later that same year, multiple lines of brass plumbing valves also meeting this standard were introduced.
Bonney Forge valves are tested to exceed the new API standards. API 602 testing on its forged valves is conducted by a third party to API 622 and cast valves are tested to validate leakage below 50 ppmv, exceeding EPA standards.
In addition to one of the industry’s broadest selections of valves for commercial plumbing and food-service operations, T&S Brass offers a full line of pressure-balancing shower valve packages.
