Operations
The Watts ACV Pressure Reducing Control Valve is designed to automatically reduce a uctuating higher
upstream pressure to a constant lower downstream pressure regardless of varying ow rates. It is con-
trolled by a normally open, pressure reducing pilot designed to: 1) Open (allowing uid out of the main valve
cover chamber) when downstream pressure is below the adjustable setpoint, and 2) Close (allowing uid to
ll the main valve cover chamber) when downstream pressure is above the adjustable setpoint. A decrease
in downstream pressure causes the valve to modulate toward an open position, raising downstream pres-
sure. An increase in downstream pressure causes the valve to modulate toward a closed position, lowering
downstream pressure.
