Anti-Surge Pump Start Control Valve
The BERMAD 730-48 is a Normally Open, Anti Surge, pilot-operated and diaphragm-actuated control valve.
It has a double-chambered actuator for positive and reliable actuation with an external lift spring, giving the valve it’s normally open characteristic. This affords the BERMAD 730-48 a zero reaction time, preempting and dissipating any pressure surge or excess air at pump start up.
Once the surge has passed and system piping pressure has normalized the 730-48 will close and will continue duty as a relief valve, relieving pressure spikes when needed, keeping the system pressure at its designed level.
The 730-48 is an autonomous valve operating under line pressure alone requiring no external power source.
