PUMP CONTROL VALVE

980 Series
Operation
The AMES Model 980-16 / 680-16 Pump Control Valve is designed to minimize the surges associated with
the starting and stopping of pumps. The valve slowly opens and closes as required to control pumping
related surges. The pump starts and stops against a closed valve.
Pump start up: When the pump is signaled to start, the 4-Way Solenoid is energized and directs uid and
pressure into the power chamber (below the diaphragm), and relieves uid and pressure from the cover
chamber (above the diaphragm). The uid and pressure relieved from the cover chamber is vented to
atmosphere or available oor drain. The valve opens at an adjustable rate, gradually admitting pumping
pressure into the distribution system. Rate of valve opening is controlled by the adjustable opening speed
control, which restricts the speed at which uid and pressure evacuate the cover chamber. The valve
remains fully open during the pumping cycle.
Pump shutdown: When the pump is signaled to shut-off, the 4-Way Solenoid is de-energized, and directs
uid and pressure into the cover chamber (above the diaphragm), and relieves uid and pressure from the
power chamber (below the diaphragm). The uid and pressure relieved from the power chamber is vented
to atmosphere or available oor drain. The valve closes at an adjustable rate, gradually reducing pumping
pressure. Rate of valve closure is controlled by the adjustable closing speed control, which restricts the
speed at which uid and pressure evacuate the power chamber. When the valve reaches the closed position,
the limit switch is actuated, turning the pump off.

Emergency Closure: The valve is equipped with a Mechanical Check Feature, which acts independent of
diaphragm position, and provides immediate closure when ow ceases.
Manual Operation: Engaging the Solenoid Manual operator simulates power to the solenoid, manually
opening the main valve. Disengaging the Solenoid Manual operator returns the valve to the closed
position.

Installation Guidelines
• Prior to installation, ush line to remove debris.
• Install valve horizontally “in line” (cover facing UP), so ow arrow matches ow 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 buttery valves, insure disc does not contact
control valve. Damage or improper valve seating may occur.
• Provide adequate clearance for valve servicing and maintenance.
• Provide adequate drain for cover chamber and power chamber discharge. Consult “Valve Cover
Capacity” chart on appropriate main valve Engineering Bulletin.
• Install pressure gauges to monitor valve inlet and outlet pressure.
• Connect Solenoid and Limit Switch to appropriate pump control panel locations and power source in
compliance with local electrical codes.
