Operation

The Watts ACV Pump Control Valve is designed to minimize the surges associated with the starting and

stopping of pumps. The valve slowly opens and closes as required to control pumping related surges. The

pump starts and stops against a closed valve.

Pump Start Up: When the pump is signaled to start, the 3-Way Solenoid is energized, directing pressure

into the cover chamber of the 3-way Accelerator Pilot. The Accelerator Pilot allows the main valve cover

chamber to be vented downstream, causing the valve to open at a controlled rate, gradually admitting

pumping pressure into the distribution system. The rate of opening is controlled by the adjustable opening

speed control, which restricts the speed of ﬂuid and pressure evacuating the main valve cover chamber.

The valve remains open during the pumping cycle.

Pump Shutdown: When the pump is signaled to turn off, the 3-Way Solenoid is de-energized, venting the

cover chamber of the 3-way Accelerator Pilot. The Accelerator Pilot allows the main valve cover chamber to

be connected to upstream pressure, causing the valve to close at a controlled rate. The valve slowly begins

to close while the pump continues to operate. The closing rate of the valve is controlled by the adjustable

closing speed control, which restricts the speed of ﬂuid and pressure entering the main valve cover chamber.

When the valve reaches the closed position, the limit switch is actuated, turning the pump off.

Hydraulic Check Feature: When the pump is turned off and downstream pressure is greater than upstream

pressure, downstream pressure is admitted to the main valve cover chamber through a check valve in the

pilot control system, closing the valve, preventing reversal of ﬂow.

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

opening the main valve. Disengaging the Solenoid Manual operator returns the valve to the closed

position.
