It’s a Watts BRV

Series BRV Combination Ball Valve and Relief Valves are used in commercial and residential applications on water heater installations. It consists of a bronze body construction with a full port (reduced port with PEX connection), nickel-plated brass ball, blowout-proof brass stem, PTFE seats, stem packing, and stem thrust bearing, Viton relief ball, stainless steel relief spring, brass adapter, and steel handle (the relief valve outlet includes a drain tube connection with PEX or compression fitting models). Series BRV has a low profile design and can be installed in any position. It is for applications that require a means to shut off the water supply to the water heater and for providing protection from excess water pressure caused by thermal expansion. Pressure Rated: 400psi. Relief Valve Pressure Settings: 75, 80, 100 or 125psi (5.2, 5.5, 6.9 or 8.6 bar).
