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. bermad sigma en/es series valves...
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. bermad sigma en/es series valves...
