Burst Control & Pressure Reducing Valve
Excessive Flow
792-U
700 Sigma Series
Waterworks
Irrigation
Hydraulically operated, diaphragm actuated burst control & pressure reducing control valve with two independent functions: When flow is below setting, it reduces higher upstream pressure to lower pre-set downstream pressure, regardless of varying demand or upstream pressure. Upon sensing flow in excess of setting, it shuts off drip tight and locks until manually reset.
