Hydraulically operated, pressure reducing control valve that reduces higher upstream pressure to lower constant downstream pressure, regardless of fluctuating demand or varying upstream pressure 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
TYPICAL PRODUCT APPLICATIONS
Pressure control of potable water supply lines in building operating under moderate conditions
Excessive pressure protection of low-grade plastic supply lines in buildings
Protection of main supply lines of high-
