Diaphragm valve BC-420-2B-P

hydraulically-operatedpilotpressure-reducing

Hydraulically operated, pressure reducing control valve that reduces higher upstream pressure to lower constant downstream pressure, regardless of fluctuating demand or varying upstream pressure. the model includes an off peak flows by-pass regulated with a Direct Acting Pressure Reducing valve mounted on the valve body. BERMAD 400 series valves are hydraulically operated, simple and reliable, globe valves with full bore hydrodynamic body providing an unobstructed flow path and superior performance. The valves balanced rolling-diaphragm assembly is vulcanized with a rugged radial seal disk construction, performing as the valves only moving part. PRODUCT FEATURES & BENEFITS High quality construction materials ensure reliable, long lasting operation Full bore valve port area and hydrodynamic body ensure unobstructed flow path; minimal pressure loss with low cavitation damage Fully supported and balanced rolling diaphragm – low actuation pressure and excellent low flow regulation performance Ensured operation after long standby periods Straightforward three major components design – easy and simple on-site inline maintenance with minimal down time 2-way pilot and control loop that continuously sense downstream pressure and immediately control the valve accordingly, providing stable, reliable and accurate pressure modulation under a wide range of flow-rate and pressure conditions Line Pressure Driven – Independent operation, no external power needed On-site adjustable pilot allows simple and easy calibration of required pressure level Iֺֺntegrated by-pass – stability in wide range of flows
