Cycle Stop Valve CSV3B-2T

Cycle Stop Valves

The Cycle Stop Valve is a patented pump control valve that makes a variable flow pump out of any standard, constant speed pump.

Manufacturer: Cycle Stop Valve
Model: CSV3B2T
Additional Information:

The CYCLE STOP VALVE model CSV3B is a pump control valve that automatically adjusts pump output to match variable flow requirements. Downstream of the CSV3B, pressure remains constant as long as demand on the system is between 5 gpm and 150gpm. As flow rates vary, the change in pressure causes the valve inside the CSV3B to modulate closer to or farther away from the valve seat. This enables the pressure downstream of the CSV3B to remain constant regardless of flow.
When there is no longer any demand on the system, the pressure on the discharge side of the valve begins to rise and the liner presses against the valve seat. The valve and seat are designed to never be able to completely seal. The non-closing seat is designed to allow flow of approximately 5 gpm. As the pressure tank slowly fills, the pressure begins to rise to the pressure switch shut off pressure. Shut off pressure must always be higher than the pressure held constant by the Cycle Stop Valve.
Regardless of tank size, the pressure downstream of the CSV3B will slowly rise to the pressure switch shut off point and the pump will shut off. As flow is again demanded from the system, the pressure tank will empty and the system pressure will drop to the pressure switch start point and the pump will start.
This valve eliminates water hammer from your system when start pressure and valve pressure are the same.
