XLC 335/435 PN 25

Flow rate solenoid controlled valve

The CSA XLC Model 335/435 limits the flow to a pre-set value, regardless of pressure variations. In case of flow rate lower than the required set point the valve will be fully opened. The valve is supplied with an orifice plate assembly, needed for the proper functioning and connected to the pilot. Thanks to a solenoid and an hydraulic accelerator the valve will open/closed in response to signals.

Applications
• Flow rate control of a tank feeding line tank with the possibility of interrupting the supply in case of alarm and emergency situations.
• Pumps protection against excessive flow conditions with the valves’ full opening or closing in response to signals.
• Avoiding excessive flow if installed on gravity lines right downstream of storage tanks, with the interruption of supply through signal to the solenoid if the valve’s circuit in case of pipe burst.
