Burst Control Valve, Excessive Flow
with Mechanical Flow Stem
790-M
700 Sigma Series
Waterworks
Hydraulically operated, diaphragm actuated, burst control valve that senses flow levels. When it senses flow in excess of settings, it shuts off and locks drip tight until manually reset. As long as flow is lower than settings, the valve remains fully open, minimizing head loss. A flow stem enables limiting valve opening stroke, precisely adjusting the required flow through the valve.
