XLC 325/425 PN 16/25

Solenoid controlled pressure relief/sustaining valve

The CSA Model XLC 325/425 is a globe pattern hydraulically operated automatic control valve that sustains, if installed in-line, and will relief if installed in derivation from the main line, the upstream pressure to a pre-set value regardless of variations in demand. Thanks to the solenoid control the valve will be able to close or open, in response to a signal sent from remote or by an external controller. If the upstream pressure decreases below the pilot set point the valve will close drip tight, assuring the proper operation also in static conditions.

Applications
• Water storage tanks regulation by means of backpressure control and closure through signals linked to sensors in case of excessive water level.
• Flow regulation acting on the upstream pressure with the possibility of valve’s closing and opening completely in response to a signal.
• Located between two pressure zones to supply the lower one through the exceeding values from upstream , with sectioning through an impulse in case of alarms and emergencies.
