Best3 4 pressure reducer
The BERMAD Adjustable Direct Acting Pressure Reducer is actuated by a pressure responsive diaphragm, which seeks to reach equilibrium between hydraulic and set spring force. It reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure. The low flow version model IR-3/4”PRV-05 provide superior solution under conditions of near zero demand.
Water Pressure Reducing Valves are used in residential, commercial, and institutional applications to reduce incoming water pressure to a lower predetermined level, thereby protecting downstream plumbing system components and reducing water consumption.
