Bernard’s Model 740 Booster-Pump control valve is a diaphragm-actuated, hydraulically-operated, active check valve that shuts off or opens fully in response to electric signals.
In order to prevent pipeline surges, it isolates the pump from the system during pump starting and stopping. No motor is required in this solenoid controlled valve that also features low cost wiring and has long-term drip tight sealing. With a wide range of pressures and voltages, it also has a flexible design for the easy addition of hydraulic features.
