Operation
The Watts ACV Two Way Flow Altitude Valve with Solenoid Override Feature is designed to open, allowing
flow into a reservoir or elevated storage tank (tank fill), and close drip tight when high water level is achieved.
The valve will also open allowing return flow (tank discharge), when upstream pressure falls below reservoir
head pressure. The Altitude Pilot remotely senses static tank head pressure (water level) through a field
installed sensing line, and directs pressure into and out of the cover chamber of the 3-way Accelerator Pilot.
When the cover of the Accelerator Pilot is pressurized, the main valve cover chamber is vented downstream
(dry drain) or to atmosphere (wet drain), causing the valve to open fully. When the cover of the Accelerator
Pilot is de-pressurized, the main valve cover chamber is connected to upstream pressure, causing the valve
to close drip tight.
As water level decreases, static tank head pressure falls below the adjustable setpoint of the Altitude Pilot,
causing it to pressurize the cover of the Accelerator Pilot, opening the valve. As water level increases, static
tank head exceeds the adjustable setpoint of the Altitude Pilot, causing it to depressurize the cover of the
Accelerator Pilot, closing the valve drip tight. Valve opening and closing speeds are separately adjustable.
The Position Indicator with Air Bleed Petcock allow for visual indication of valve position, and allows easy
venting of air entrapped in the main valve cover chamber.
When upstream pressure falls below reservoir head pressure, a Check Valve installed in the pilot control
system “Return Flow Line” opens, connecting the main valve cover chamber to the upstream pressure
zone, causing the valve to open allowing reservoir pressure to return into the upstream pressure zone (Tank
Discharge).
The Solenoid Override Feature provides remote electrical, or local manual closure of the valve. When
the Solenoid Pilot is energized, it vents the cover of the Accelerator Pilot, causing the main valve to close
regardless of water level. Engaging the Solenoid Manual operator simulates power to the solenoid,
manually closing the main valve. Disengaging the Solenoid Manual operator returns the valve to normal
on-off service.
Specify Tank height and Solenoid voltage PRIOR to ordering.
