Altitude control valve figure XLC 370/470 PN 16/25

The CSA Model XLC 370/470 is a globe pattern hydraulically operated automatic valve that maintains the constant level of a reservoir and water tower, regardless of upstream pressure variations, acting with an accuracy of few cm of water column. The modulating control ensures a smooth regulation and absence of water hammer, as the valve will react proportionally to the variations in demand.
