The CYCLE STOP VALVE models CSV1 are patented pump control valves that automatically adjust pump output to match variable flow requirements. Downstream of the CSV1, pressure remains constant as long as demand on the system is between 1 and 25 gpm. As flow rates vary, the valve inside the CSV1 moves closer to or farther away from the valve seat. This enables the pressure downstream of the CSV1 to remain constant regardless of flow.

When there is no longer any demand on the system, the pressure begins to rise and the valve is pressed against the valve seat. The non-closing seat is designed to allow flow of approximately 1 gpm. As flow continues past the seat, 1 gpm begins to enter the pressure tank placed downstream of the CSV1. As the pressure tank slowly fills, the system pressure begins to rise to pressure switch shut off pressure. Pressure switch shut off pressure must always be set higher than the pressure regulated by the CSV1. Maximum pump shut off pressure cannot be higher than 150 PSI and pressure differential cannot be more than 125 PSI.

 Regardless of tank size, as the tank fills, the pressure downstream of the CSV1 will slowly rise to the pressure switch shut off point and the pump will be shut off. As flow is again demanded from the system, the pressure tank will empty and the pressure switch will start the pump.

This valve eliminates water hammer in your system when start pressure and valve pressure are the same. The CSV1 is recommended for potable water systems and does not tolerate bacteria, algae, or sand abrasion. It is very important that this model not be put in a bind as it will bend in the middle and begin to squirt water until it is straightened back up.

Important note: Over time, (how long depends on water quality) the CSV1 can begin to vent water to atmosphere. (The valve will not leak when the pump is not running as the weep is a function of the valve actuating and not a leak). Ideally, this valve is installed inside your well or in a place where a weep of water will not pose problems.  The CSV1 valve will function correctly whether it is venting air or water. If this “weeping” is not acceptable for your application, consider the  Cycle Stop Valve CSV1Z.  The CSV1Z better tolerates bacteria, algae, and abrasives and does not vent water to atmosphere.
