The valves used in commercial and industrial water delivery systems need to not only be safe, but also durable enough to stand up to high loads. A family of NSF lead-free brass valves from GF Piping Systems is designed to handle those high loads and strong flow rates. Valve styles include pressure reducing, thermostatic balancing and thermostatic mixing.

“We are pleased to add these five high-quality brass valves to our traditionally all-thermoplastic valve product line,” says Ralph Abdelhak, product manager of GF Piping Systems. “The three valve styles provide different solutions for water systems in high-rise buildings, multifamily dwellings, hospitals, hotels, sports facilities, universities, dormitories and industrial buildings.” 

First in the family are the compact, direct-acting Pressure Reducing Valves Type 1319 and 1339. The two PRVs feature excellent control characteristics, even at low flow rates. This patented design, which offers a 416 stainless steel floating seat and modular construction, allows for a more compact size. The EPDM diaphragm and seals provide superior resistance to strong and oxidizing disinfectants such as chlorine. Available in 1/2- to 2 1/2-inch sizes, these valves handle hot-water temperatures up to 158 degrees F and inlet pressures up to 357 psi, and they comply with NSF 61 and NSF 372. They include a choice of two pressure control ranges, easy cleaning and downstream pressure gauge ports standard on both sides. 

Next in the family is the Type 6320 Thermostatic Balancing Valve. The balancing valve regulates the flow rate in hot-water (up to 158 degrees F) circulating systems by continuously sensing the return water temperature with an integrated thermostat, ensuring consistent system temperature. This low-maintenance 3/4-inch valve includes field-adjustable temperature setpoints, 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.

Last in the new family are the Thermostatic Mixing Valves Type 3409 and 3419, which 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 integrated circulation inlet saves installation labor and materials. Other performance attributes include scald protection, energy savings, capability to operate without an external power supply and field-adjustable outlet temperature ranges.
