NSF lead-free valve family for commercial water applications
This company has introduced a family of NSF lead-free brass valves (photo) designed to handle high loads and strong flowrates in commercial-grade and light-industrial water-distribution applications. Valve styles include pressure reducing, thermostatic balancing and thermostatic mixing. The compact, direct-acting Pressure Reducing Valves (PRV) Type 1319 and 1339 feature excellent control characteristics, even at low flowrates. This patented design, which offers a 416 stainless-steel floating seat and modular construction, allows for a more compact size. The Type 6320 Thermostatic Balancing Valve regulates the flowrate in hot (up to 158°F) water circulating systems by continuously sensing the return water temperature with an integrated thermostat, ensuring consistent system temperature. The Thermostatic Mixing Valves Type 3409 and 3419 accurately deliver tempered water to hot-water-distribution systems. — GF Piping Systems, Irvine, Calif.

This diaphragm valve touts reduced maintenance
The EnviZion valve (photo) has embedded technologies that allow for a more streamlined installation and maintenance process, delivering less downtime, longer preventative maintenance cycles and greater production capacity for manufacturers. An integrated thermal-compensation system provides a constant sealing force, helping to eliminate the effects of thermal cycling. The EnviZion diaphragm can withstand the wear of production cycles and maintains a reliable seal, minimizing the risk of leakage and batch contamination. The EnviZion valve delivers increased productivity by keeping operations online and running longer, as well as reduced operating costs yielding over 90% reduction in maintenance time, says the company. — ITT Engineered Valves, Lancaster, Pa.
