Constant Pressure pump control valves
The CSV system uses a very small pressure tank, usually containing 1 gallon of water or more, to allow a well pump or a booster pump to remain off during small requirements for water. The CSV will also work with larger tanks but, since the CSV controls the pressure and flow, large pressure tanks are not required.
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.
