Bermad WW-790-M Large Metal Hydraulic Burst Control Safety Valve

The Model 790-M Burst Control Valve is a hydraulically-operated, diaphragm-actuated, control valve that—upon sensing flow in excess of setting—shuts off and locks drip tight until it is manually reset.

As long as the flow is lower than the setting, the valve remains fully open, minimizing head loss.
