Cycle Stop Valve CSV1Z Constant Pressure Pump Control Valves

CSV1W / CSV1Z / CSV2W General Information

The Cycle Stop Valve model CSV1W, CSV1Z, and CSV2W are pump control valve that automatically adjust pump output to match variable flow requirements. Downstream of the CSV1W, CSV1Z, and CSV2W, pressure remains constant as long as demand is between the upper and lower limits of the valve. The 1" CSV1W and CSV1Z handle from 1-25 GPM and the 1 1/4" CSV2W handles from 5-50 gpm.

As flow rates vary, the change in pressure causes the valve inside these models to modulate closer to or farther away from the valve seat. This enables the pressure downstream of the CSV to remain constant depending on pressure fall off. Cycle Stop Valve CSV2W

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 valve and seat are designed to never be able to completely seal. The non-closing seat is sized to allow flow of approximately 1 gpm on the 1" valves or 5 gpm on the 1 1/4" valve. As this flow continues past the seat, water begins to fill the pressure tank downstream of the CSV. As the pressure tank slowly fills, the system pressure will slowly rise to pressure switch shut off. (Note: Pressure switch shut off pressure must always be higher than the constant pressure held by the CSV).

Cycle Stop Valve CSV3B Regardless of tank size, when the tank fills, the pressure downstream of the CSV rises to 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.

Model CSV1Z and CSV1W are dual threaded and are available in 1" female NPT/1 1/4" male NPT. The "Z" model is adjustable from 15-150 PSI, the "1W" model is preset to 60 PSI and is adjustable from 40-100 PSI. The CSV2W is available in 1 1/4" female NPT thread and has pressure settings available from 25-75 PSI or 50-120 PSI. There can be no more than 125 PSI maximum differential pressure across any of these valves. (Difference in pressure between inlet pressure and outlet pressure).

Cycle Stop Valve CSV150 Cycle Stop CSV150 and CSV160

The CYCLE STOP VALVE models CSV1/1.25 are patented pump control valves that automatically adjust pump output to match variable flow requirements. Downstream of the CSV1 and CSV1.25, pressure remains constant as long as demand on the system is between 1 and 25 gpm for the 1” and 2-50 gpm for the 1 1/4”. 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 CSV1/1.25 to remain constant regardless of flow.

Model #: CSV150 / Size: 1" / Max GPM: 25 GPM / Type: Threaded / Preset Pressure Setting: 50 PSI

Model #: CSV160 / Size: 1" / Max GPM: 25 GPM / Type: Threaded / Preset Pressure Setting: 60 PSI

Cycle Stop Valve CSV1Z Model CSV1Z

Dual threaded and are available in 1" female NPT/1 1/4" male NPT. The "Z" model is adjustable from 15-150 PSI..

There can be no more than 125 PSI maximum differential pressure across any of these valves. (Difference in pressure between inlet pressure and outlet pressure).

Model #: CSV1Z / Size: 1" / Max GPM: 25 GPM / Type: Threaded / Pressure Adjustment Range: 15-150 PSI

The CSV2W

1 1/4" female NPT thread and has pressure settings available from 25-75 PSI or 50-120 PSI.

There can be no more than 125 PSI maximum differential pressure across any of these valves. (Difference in pressure between inlet pressure and outlet pressure).

Model #: CSV2W1.25T50120 / Size: 1 1/4" / Max GPM: 50 GPM / Type: Threaded / Press. Adj. Range: 50-120 PSI

Cycle Stop Valve CSV3B Model CSV3B

Single chamber diaphragm operated valve available in 2" and 3" threaded or flanged, and 4" through 12" flanged with flow rates available from 5 gpm to 5000 gpm. Model CSV3B valves size 2" is adjustable from 25-175 PSI and 3" through 12" are adjustable between 15-150 PSI. There can be no more than 125 PSI differential pressure (Difference in pressure between inlet pressure and outlet pressure). CSV3B valves are available in straight in line globe style. The standard CSV3B is made of polyester coated cast iron with stainless and bronze trim.

Model #: CSV3B2T / Size: 2" / Max GPM: 150 GPM / Type: Threaded / Adjustment range: 25-175 PSI

Cycle Stop Valve CSV3R Model CSV3R2F

The Cycle Stop Valve model CSV3R is a patented pump control valve that automatically adjusts pump output to match variable flow requirements. Downstream of the CSV3R, pressure remains constant as long as demand on the system is between 5 gpm and the maximum pump output. As flow rates vary, the change in pressure causes the liner inside the CSV3R to modulate closer to or farther away from the grillwork area and seating surface. This enables the pressure downstream of the CSV3R to remain constant regardless of flow.

Model #: CSV3R2F / Size: 2" / Max GPM: 150 GPM / Type: Wafer / Pressure Adjustment Range: 25-175 PSI
