Diaphragm valve BC-430-P

hydraulically-operated2-waycalibration

Pressure relief/sustaining hydraulically operated control valve that can fulfill either of two separate functions: When installed in-line, it sustains minimum pre-set, upstream (back) pressure regardless of fluctuating flow or varying downstream pressure. When installed as a branched from the line circulation valve it relieves excessive line pressure when above maximum pre-set. 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 upstream 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
