Bermad - Model 720-DC1 - Full Modulating Pressure Reducing Valve

Hydraulically operated, full modulation pressure reducing solution that reduces higher upstream pressure to lower downstream pressure, based on flow or time windows, regardless of fluctuating demand or varying upstream pressure. BERMAD 700 SIGMA EN/ES series valves are hydraulic, oblique pattern, globe valves with a raised seat assembly and double chamber unitized actuator, that can be disassembled from the body as a separate integral unit. The valves hydrodynamic body is designed for unobstructed flow path and provides excellent and highly effective modulation capacity for high differential pressure applications. The 720-DC1 is equipped with DELTA a stand-out pressure management controller for system optimization. It provides a calmer network, an improved efficiency and a reduction of leakage and bursts. The end result is a reliable water supply and better service for the client. The DELTA is a fully remote controlled fail safe battery operated controller. The DELTA logs the data and uses cyber secured technology to transmit the data to a user-friendly cloud platform.
