Operation
The Watts ACV Solenoid On-Off Control Valve with Hydraulic Check Feature is designed to open fully or
close drip-tight as commanded by the 3-Way Solenoid Pilot, and close drip-tight when downstream pressure
becomes greater than upstream pressure. The Solenoid Pilot directs upstream 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. Valve opening and closing speeds are
separately adjustable. Engaging the Solenoid Manual operator simulates power to the solenoid, manually
controlling the main valve. Disengaging the Solenoid Manual operator returns the valve to electrical on-off
service.
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 On-Off operation
resumes when upstream pressure exceeds downstream pressure.
Specify voltage and MAIN VALVE actuation (energize to open or close), and “wet” or “dry” drain
PRIOR to ordering.
Installation Guidelines
• Prior to installation, flush line to remove debris.
• Install valve horizontally “in line” (cover facing UP), so flow arrow matches flow through the line. Avoid
installing valves 6” and larger vertically. Consult factory prior to ordering if installation is other than
described.
• Install inlet and outlet isolation valves. NOTE: When using butterfly valves, insure disc does not contact
control valve. Damage or improper valve seating may occur.
• Provide adequate clearance for valve servicing and maintenance.
• Install pressure gauges to monitor valve inlet and outlet pressure.
• Provide adequate drain for cover chamber discharge if “wet drain” option is selected. Consult “Valve
Cover Capacity” chart on appropriate main valve Engineering Bulletin.
• Connect Solenoid Pilot to appropriate power source in compliance with local electrical codes.
