Pressure Relief/Sustaining Valve 1030-55

Solenoid controlled valve that can be set to close drip tight or modulate as pressure relief or sustaining in response to an electric signal. When modulating the valve sustains minimum pre-set, upstream pressure. If installed as a “branched from the line” it relieves excessive line pressure when above maximum pre-set. The BERMAD 1000 is at the leading edge of control valve design, providing a valve that is free of the typical limitations associated with standard control valves. A unitized flexible diaphragm & guided plug provide a significantly ‘look through’ passage resulting in accurate & stable regulation and high flow capacity. The 1000 unique composite structure allows fast & simple maintenance by easy replacing of lightweight diaphragm assembly. It has a wide range of end connection types and sizes, including articulated flange connections isolating the valve from pipeline bending & pressure stresses.
