Jomar Valve's thermal expansion relief valve is the perfect replacement for an expansion tank, the company states. 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” Barb, a 1/2” Pex and a 3/8” 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. Jomar Valve. | www.jomarvalve.com
