Commercial & Industrial Regulator
The RB 4000 pressure regulator is designed for industrial applications, district station applications, and large appliance regulation where fast response is required. The balanced valve design provides constant outlet pressure under all inlet pressure conditions. The unique built-in pulsation dampener allows for almost infinite flow rate turn-down.
All types are fitted with a mistake-proof SSV by-pass. A robust, efficient noise abatement cage can also be incorporated (optional).
