Webstone®, a brand of NIBCO, announces new patent-pending Dielectric Water Heater Supply Valves™ (DWHSV). These Pro-Pal® step-saving valves simplify the installation and service of any water heater, combining a dielectric union, a ball valve, and a ½” FIP vacuum relief valve port into a single forged dezincification resistant brass body.
For areas where an expansion tank is also required, the Dielectric Water Heater Supply Valve with Expansion Tank Service (DWHSV-X) is a fully integrated solution. It features an extended arm with a ¾” FIP port and ¾” capped hose drain. Both models are available with or without the vacuum relief valve and your choice of FIP, MIP, sweat, press, or push ends to connect to system piping.
