Operations
The Watts ACV On-Off Float Control Valve is designed to open fully or close drip-tight as commanded by
the Float Control Pilot. The Float Pilot may be either valve or remote mounted. The valve closes drip tight
when water level reaches the adjustable high-level setpoint, and opens fully when water level is below the
adjustable low-level setpoint, allowing a calculated “draw-down” of water level to increase tank circulation.
The On-Off Float Pilot commands the routing of uid and pressure into and out of the cover chamber of the
main valve. When water level reaches the adjustable high-level setpoint, the Float Pilot connects the cover
chamber of the valve to upstream pressure, closing the valve drip tight. The valve remains closed as water
level decreases. When water level reaches the adjustable low-level setpoint, the Float Pilot connects the
cover chamber of the valve to atmosphere (wet drain), opening the valve fully. High and low levels are sepa-
rately adjustable by positioning stop collars on the oat rod(s) at desired opening and closing setpoints.
If desired, the on-off action of the valve can be “reversed” by modifying the hydraulic connections of the
On-Off Float Pilot.
