New Thermal Expansion Relief Valves

In our continuing effort to expand our offering of valves and water heater connectors, Sioux Chief introduces a new line of Thermal Expansion Relief Valves. These new items are in-stock and ready to ship.

These full-port valves are available independently (648 Series), or as part of a 633 Series water heater connector, with a rigid copper extension and FIP swivel connection. Valves have CPVC socket, F1960 PEX, or F1807 PEX connections, while the relief outlet is available with compression, hose barb, or PEX connections. The 1/4-turn valves are made from top-quality brass material and have easy-grip, red anodized aluminum handles.

Along with the other great features, these thermal expansion relief valves can satisfy code requirements for thermal expansion control easier and with lower material costs than traditional expansion tanks.
