Operation

The Watts ACV Pressure Sustaining and Solenoid (On-Off) Control Valve with Hydraulic Check Feature is

designed to permit ﬂow when upstream pressure is above the adjustable setpoint of the control pilot, and

throttle toward closed when upstream pressure falls below the adjustable setpoint. It is controlled by a

normally closed control pilot designed to: 1) Open (allowing ﬂuid out of the main valve cover chamber) when

upstream pressure is above the adjustable setpoint, and, 2) Close (allowing ﬂuid to ﬁll the main valve cover

chamber) when upstream pressure is below the adjustable setpoint. An increase in upstream pressure

causes the valve to modulate toward an open position. A decrease in upstream pressure causes the valve

to modulate toward a closed position.

The Solenoid Pilot will either open to allow regulating action, or close the valve drip-tight when energized.

Specify energize to open or close the Main Valve and voltage PRIOR to ordering.

If downstream pressure becomes greater than upstream pressure, downstream pressure is admitted to

the main valve cover chamber, closing the valve and preventing reversal of ﬂow. Normal backpressure or

sustaining operation resumes when upstream pressure exceeds downstream pressure.

When the valve is located “in line” connecting two distribution zones, the valve acts as a Pressure

Sustaining Control Valve. When pressure in the upstream zone falls below the pilot setting, the valve

modulates toward a closed position, sustaining pressure in the upstream zone. The valve will close, if

necessary, until upstream pressure is above the pilot setting. The valve should be speciﬁed to include the

optional opening speed control and position indicator when used for Pressure Sustaining applications.
