What Are Cycle Stop Valves?

Normally when a pump runs it discharges at a constant rate of flow out into the main line of the house, even if that pressure even if that rate is higher than the rate water is exiting the line. This is where the cycle stop valve comes in. The valve is designed to choke back the output of the pump to match the flow requirements coming from the main line. As the demand increases, the flow from the pump increases. The cycle stop valve can operate from as little as 1GPM to as much as the pump is capable of producing, thereby creating a variable speed pump from an ordinary pump without expensive pump controls or electronics.

Cycle stop valves are available in 1" and 1-1/4" with flow rates from 1GPM to 50GPM.

Features

  • Smaller Pressure Tank Size: Because the cycle stop valve regulates flow on it's own, the pump stays on longer even without a large pressure tank. However a pressure tank is still needed to provide pressure to the line.
  • Eliminate Premature Pump Failure: Premature pump failure is reduced by eliminating pump cycling which is hard on the pump motor and increases electricity usage.
  • Decreased Electrical Usage: As the cycle stop valve chokes back water flow from the pump, a back pressure is created. This actually helps to reduce load on the pump and thereby reduces the current draw of the pump motor. It also helps your pump stay cooler!
  • Completely Mechanical: The cycle stop valve is completely mechanical and has no electrical or electronic components. This means that even though technology may change, your cycle stop valve will never become obsolete.
