B&G dual unit valves are a combination of a pressure reducing valve and a relief valve. For filling hot water boilers and associated system piping systems to a properly controlled pressure after boiler installation or servicing. It is not a safety device and not intended to be used as a water feed valve to control boiler water at a safe operation level or pressure. The relief valve is set at 30 psig. The reducing valves are pre-set at 12 psig and adjustable from 10 to 25 psig. The relief valve provides fill over-pressure protection.
