PUMP CONTROL VALVE
980-16-19
680-16-19
Operation
The AMES Model 980-16-19 / 680-16-19 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 3-Way Solenoid is energized and pressurizes
the cover chambers of each 3-Way Accelerator Pilot. Accelerator Pilot (2B) directs fluid and pressure into
the power chamber (below the diaphragm), and Accelerator Pilot (2A) 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 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 fluid 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 3-Way Solenoid is de-energized, relieving
pressure from the cover chambers of each 3-Way Accelerator Pilot. Accelerator Pilot (2A) directs fluid
and pressure into the cover chamber (above the diaphragm), and Accelerator Pilot (2B) relieves fluid and
pressure from the power chamber (below the diaphragm). The fluid and pressure relieved from the power
chamber is vented to atmosphere or available floor 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 fluid 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 flow 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.
