Constant pressure pump control for variable demand irrigation - Water & Wastewater - Irrigation

Mist, Drip, Spray, or Big Guns, the Cycle Stop Valve (CSV) turns any Submersible, Turbine, or Centrifugal pump into a variable flow, constant pressure system. The CSV maintains a constant pressure on the irrigation system throughout a wide range of flow. Eliminating line breaks and leaks, while precisely applying an exact amount of water, the CSV can conserve water as well as energy.

The CSV has state of the art technology, designed to mimic the “constant pressure” control of Variable Frequency Drive VFD, or “so called” constant pressure pumps. Requiring no electronics, and therefore using no extra power, the CSV eliminates the problems long associated with VFD control.

The pressure controlled CSV reacts extremely fast to changes in the system demand. This counteracts negative and positive transient pressure waves, by cancelling them out with an equal and opposite pressure wave. Eliminating transient pressure waves, and the subsequent water hammer they cause, can conserve vast amounts of water and energy. Eliminating water hammer also helps keep the pipe in the ground and eliminates expensive repairs.
