Operation
The Watts ACV Pump Control Valve with Backpressure Feature 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, and throttles to maintain a minimum backpressure against the pump during the pumping
cycle. 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.
Backpressure Feature: During the pumping cycle, the valve acts as a Backpressure Control Valve. When
pump discharge pressure falls below an adjustable minimum, the valve modulates toward a closed position,
increasing backpressure against the pump. Throttling (Backpressure) action is controlled by a normally
closed control pilot designed to: 1) Open (allowing fluid out of the main valve cover chamber) when pump
discharge pressure is above the adjustable setpoint, and, 2) Close (allowing fluid to fill the main valve cover
chamber through the integral orifice of the Accelerator Pilot) when pump discharge pressure is below the
adjustable setpoint. An increase in pump discharge pressure causes the valve to modulate toward an open
position. A decrease in pump discharge pressure causes the valve to modulate toward a closed position.
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.
