XLC 324/424 PN 16

Pressure relief/sustaining valve with minimum-maximum level control

The CSA Model XLC 324/424 is a globe pattern hydraulically operated automatic control valve that sustains the upstream pressure to a pre-set value regardless of variations in demand and, at the same time, it controls and regulates the minimum and maximum level inside a tank. In case of decrease of the upstream pressure below the set point, during opening, the valve will throttle ensuring the water supply to higher zone consumers. The CSA XLC 324/424 is extremely important to stabilize HGL, contain unwanted surges and to limit the excessive flow to the tank.
