The Cycle Stop Valve Constant Pressure System is an effective way to have steady water pressure, reduced pump cycling, and a reduced pressure tank size all without using a variable frequency drive (VFD) constant pressure system.
The CSV1A Stainless Steel Cycle Stop Valve can automatically adjust pump output to match variable flow requirements. It is a pressure adjustable valve, and can handle from 1-25 GPM.

Product Features
Advantages:
· Constant water pressure
· Reduce pump cycling to extend pump life
· Small pressure tank
· Easier maintenance than VFD system
The maximum flow rate and maximum Well water pressure tanks depends on the pump's performance
Pressure setting:
· Cycle Stop Valve pressure should be between cut-in and cut-off of pressure switch
· Cycle Stop Valve pressure should be at least 10 psi below cut-off pressure
· It is suggested to have the Cycle Stop Valve pressure 5 psi higher than cut-in pressure
· The air pressure for the pressure tank should be 5 psi below the cut-in pressure
-----------------------------------------------------------------------------------------------------------------
For example, here are the ideal settings for a 55 psi constant pressure system:
Cycle Stop Valve pressure: 55 psi
Pressure Switch: cut-in 50 psi / cut-off 70 psi
Pressure Tank: 45 psi (AIR)
How it works:
Faucet on, Water pressure drop from 70 psi to 50 psi, Pump starts, Water pressure would keep at 55 psi, Faucet off, Water pressure raise to 70 psi, Pump stop
Please Note: The installation package comes unassembled.
The Cycle Stop Valve model CSV1A is a pump control valve that automatically adjust pump output to match variable flow requirements. Downstream of the CSV1A pressure remains constant as long as demand is between the upper and lower limits of the valve. The 1" CSV1A handle from 1-25 GPM.
