Operation
The AMES Model 930-01-19 / 630-01-19 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.
