Operation

The Watts ACV Deep Well Pump Control Valve is designed to minimize the surges associated with the

starting and stopping of well pumps. The valve slowly opens and closes as required to control pumping

related surges. The pump starts and stops against an open valve.

Pump start up: When the pump is signaled to start, the 4-Way Solenoid is energized and directs ﬂuid and

pressure into the cover chamber (above the diaphragm), and relieves ﬂuid and pressure from the power

chamber (below the diaphragm). The ﬂuid and pressure relieved from the cover chamber is vented to

atmosphere or available ﬂoor drain. The valve closes at an adjustable rate, gradually admitting pumping

pressure into the distribution system. Rate of valve closure is controlled by the adjustable closing speed

control, which restricts the speed at which ﬂuid and pressure evacuate the power chamber. The valve

remains closed during the pumping cycle.

Pump shutdown: When the pump is signaled to shut-off, the 4-Way Solenoid is de-energized, and directs

ﬂuid and pressure into the power chamber (below the diaphragm), and relieves ﬂuid and pressure from the

cover chamber (above the diaphragm). The ﬂuid and pressure relieved from the cover chamber is vented

to atmosphere or available ﬂoor drain. The valve opens at an adjustable rate, gradually reducing pumping

pressure, allowing the system check valve to slowly close. Rate of valve opening is controlled by the

adjustable opening speed control, which restricts the speed at which ﬂuid and pressure evacuate the cover

chamber. When the valve reaches the full open position, the limit switch is actuated, turning the pump off.

Manual Operation: Engaging the Solenoid Manual operator simulates power to the solenoid, manually

closing the main valve. Disengaging the Solenoid Manual operator returns the valve to the open position.
