Jomar Valve's Thermal Expansion Relief Valve (JF-100RVG) is the perfect replacement for an expansion tank. The JF-100RVG is a combination isolation and pressure relief valve. With the ability to customize the valve end connections, relief connections, and pressure ratings, the JF-100RVG is extremely versatile. Available with factory set points of 80, 100, or 125 PSI and a patent-pending O-Ring connection design, every valve includes a 3/8-inch Barb, a 1/2-inch Pex, and a 3/8-inch Compression connection in the box — making inventory easy. The threaded and PEX-A valves are currently available, with the solder and PEX-B coming soon.
