ABSTRACT:
A pump check valve control apparatus includes a pump for delivering a fluid to a system. A valve between the pump and the system controls the delivery of the fluid to the system. A valve actuator, signalled by an actuator control, begins to open the valve when the pressure on the pump side of the valve substantially equals the system pressure. During the opening cycle of the valve, a substantially constant pressure is maintained in the system. The actuator control closes the valve so that flow through the valve ceases when the pressure differential across the valve is substantially zero.
