Operations
The Watts ACV Pressure Reducing Control Valve with Low Flow By-Pass is designed to automatically reduce a
uctuating higher upstream pressure to a constant lower downstream pressure regardless of varying ow rates. It
is controlled 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 pressure. An increase in
downstream pressure causes the valve to modulate toward a closed position, lowering downstream pressure.
A Low Flow By-Pass Valve is piped parallel to the Main Pressure Reducing Valve, and is set approximately 10 PSI
higher. The Low Flow By-Pass handles ow requirements below the range of the Main Pressure Reducing Valve.
During “off peak” demand conditions, the Low Flow By-Pass provides ow and pressure to the downstream zone.
As ow requirements increase beyond the capacity of the Low Flow By-Pass, downstream pressure falls below the
setpoint of the Main Pressure Reducing Valve allowing it to throttle toward open, supplementing ow and pressure.
As ow requirements decrease, downstream pressure rises above the setpoint of the Main Pressure Reducing Valve,
causing it to throttle toward closed, allowing the Low Flow By-Pass to resume command of ow and pressure.
