Operation
The AMES Model 985 / 685 Deep Well Pump Control Valve is designed to minimize the surges associated
with the starting and stopping of well pumps. The valve slowly opens and closes as required to control
pumping related surges. The pump starts and stops against an open valve.
Pump start up: When the pump is signaled to start, the 4-Way Solenoid is energized and directs fluid and
pressure into the cover chamber (above the diaphragm), and relieves fluid and pressure from the power
chamber (below the diaphragm). The fluid and pressure relieved from the cover chamber is vented to
atmosphere or available floor drain. The valve closes at an adjustable rate, gradually admitting pumping
pressure into the distribution system. Rate of valve closure is controlled by the adjustable closing speed
control, which restricts the speed at which fluid and pressure evacuate the power chamber. The valve
remains closed during the pumping cycle.
Pump shutdown: When the pump is signaled to shut-off, the 4-Way Solenoid is de-energized, and directs
fluid and pressure into the power chamber (below the diaphragm), and relieves fluid and pressure from the
cover chamber (above the diaphragm). The fluid and pressure relieved from the cover chamber is vented
to atmosphere or available floor drain. The valve opens at an adjustable rate, gradually reducing pumping
pressure, allowing the system check valve to slowly close. Rate of valve opening is controlled by the
adjustable opening speed control, which restricts the speed at which fluid and pressure evacuate the cover
chamber. When the valve reaches the full open position, the limit switch is actuated, turning the pump off.
Manual Operation: Engaging the Solenoid Manual operator simulates power to the solenoid, manually
closing the main valve. Disengaging the Solenoid Manual operator returns the valve to the open position.
