Overview: Hydraulic control valve

Model XLC410 - Downstream pressure reducing or stabilizing
The CSA XLC 410 Series control valve will reduce and stabilize the downstream pressure to a preset value, regardless of variations in demand and upstream pressure fluctuations.


Model XLC420 - Upstream pressure sustaining or relief
The CSA XLC 420 control valve will sustain, if installed in-line, and relief if installed in derivation from the main line, the upstream pressure to a pre-set value regardless of variations in demand.


Model XLC430 - Flow control
The CSA XLC 430 Series flow control valve will automatically limit the flow to a preset value, regardless of pressure variations. In case of flow rate lower than the required set point the valve will be fully opened.


Model XLC440 - Minimum/Maximum level control
The CSA XLC 440 minimum-maximum level control valve will automatically operate an on-off regulation to maintain the tank level within an adjustable range.


Model XLC450 - Solenoid operated "on/off" control loop
The CSA XLC 450 solenoid control valve will either open or close in response to the signals to the solenoid valves.


Model XLC453 - Solenoid operated "step by step" control loop
The CSA XLC 453 step by step solenoid control valve will perform a regulation in response to the signals sent to the solenoid valves.This valve is usually installed in combination with a PLC or managed directly from a remote monitoring system.


Model XLC460 - Constant level control valve
The CSA XLC 460 constant level control valve will automatically maintain the tank level within a range of approximately 15 cm.


Model XLC470 - Altitude control valve
The CSA XLC 470 altitude control valve will maintain the level of a water tower or a tank, with an accuracy of a few cm of water column.The altitude control is regardless of any upstream pressure variations.
