NSF lead-free brass valves handle high loads and strong flow rates in commercial grade and light industrial water distribution applications. Valve styles include pressure reducing, thermostatic balancing, and thermostatic mixing.
Pressure Reducing Valves Type 1319 and 1339 feature excellent control characteristics, even at low flow rates. This patented design offers a 416 stainless steel floating seat and modular construction to allow for a more compact size. The EPDM diaphragm and seals provide superior resistance to strong and oxidizing disinfectants such as chlorine. Available in sizes 1/2 to 2-1/2 in., these valves handle hot water temperatures up to 158°F, inlet pressures up to 357 psi, and comply with NSF 61 and NSF 372. Other characteristics include a choice of two pressure control ranges, easy cleaning, and downstream pressure gauge ports standard on both sides.
Type 6320 Thermostatic Balancing Valve regulates the flow rate in hot water (up to 158°F) circulating systems by continuously sensing the return water temperature with an integrated thermostat, ensuring consistent system temperature. This low maintenance 3/4-in. valve features field adjustable temperature set points, overheat protection, and simple regulator operation. Regulating the flow rate to meet temperature setpoints allows for a shorter heat-up phase after temperature drop, increasing energy savings.
Thermostatic Mixing Valves Type 3409 and 3419 accurately deliver tempered water to hot water distribution systems. Mountable in any position, the two mixing valves are ASSE 1017 compliant when installed with a check valve or combination check/stop on the hot and cold water inlets. The unique, integrated circulation inlet saves installation labor and materials. Other performance attributes include scald protection, energy savings, the capability to operate without an external power supply, and field adjustable outlet temperature ranges.
