XLC 340/440 PN 16

Minimum-maximum level control valve

The CSA Model XLC 340/440 is a globe pattern hydraulically operated automatic control valve that regulates the minimum-maximum level of a tank, with an adjustable range, regardless of upstream pressure variations. Thanks to a CSA needle valve the reaction time can be adjusted, to prevent water hammer effects during the closing phase.
