Operation
The AMES Model 910-15 / 610-15 Combination Pressure Reducing and Solenoid On-Off Control Valve is
designed to automatically reduce a fluctuating higher upstream pressure to a constant lower downstream
pressure regardless of varying flow rates, and open, allowing regulating action, or close drip-tight as
commanded by the Solenoid Pilot. It is controlled by a normally open, pressure reducing pilot designed
to: 1) Open (allowing fluid out of the main valve cover chamber) when downstream pressure is below the
adjustable setpoint, and 2) Close (allowing fluid to fill 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.
The Solenoid Pilot will either open to allow regulating action, or close the valve drip-tight when energized.
Specify energize to open or close the Main Valve and voltage 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” or higher 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.
• If installation is subjected to very low flow or potentially static conditions, AMES recommends a pressure
relief valve (1/2”minimum) be installed downstream of the Pressure Reducing Valve for additional system
protection.
• Connect Solenoid to proper electrical source in compliance with local electrical codes.
