摘要

Improved regulating valve, applicable to water softeners, characterized in that it involves a succession of chambers, controlled by two shutters fixed to a rod displaceable by the action of a membrane also attached to the stem that will position it depending on how the circulating pressure acts on it in the valve, causing as a consequence the intercommunication or isolation of the cameras.
