Pressure Sustaining Valve with Solenoid Control
730-55
700 Sigma Series
Waterworks
Irrigation
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. The valve either regulates or shuts off in response to an electric signal.
