Pump off: When the pump is off the Auxiliary 3-way Valve keeps the valve in a closed position.

Starting sequence: The pump starts against a closed valve. When the working pump rate is reached the Solenoid Control gradually opens the valve to prevent pump surge.

Stopping sequence: The pump stops when the valve is totally closed. The shut-off signal de-energizes the Solenoid Control to let the valve close gradually. Meanwhile the pump is still working. When the valve is fully closed the Switch Assembly shuts the pump off.

Emergency sequence: In case of a power failure (P2 > P1), the valve closes fast to protect the pump. The Pressure Relief Valve or Surge Anticipator Valve is usually combined with the pump control valve in order to dissipate surge pressures.
