Check Control Valve
Check control valves are used to allow fluid through the valve in only one direction. Once the liquid or gas enters the valve, it may only exit at the other end.
Apco Automatic Control Check Valves are Excellent where Pump Discharge Control is essential, due to high velocities (10 FPS or more), and high pressures (over 100 PSI). Electrically operated, to permit remote control of automatic pump stations. during electrical power loss, this valve will automatically shut-off, without assistance.

The Automatic Control Check Valve is a unique Check Valve. It is recommended where pump flow control is essential to prevent pressure surges during pump start-up and shut-down. The valve (disc) is electrically controlled to permit remote operation from automatic pump stations. The valve functions as a shut-off valve, slowly opening after the pump starts and slowly closing when stopping the pump flow. Should loss of electrical power occur, the valve will automatically shut-off without any auxiliary power supply.
