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.

Product features
• Body and cover in ductile cast iron GJS 450-10. • Internals in ductile cast iron GJS 450-10 and stainless steel. • Position indicator in stainless steel. • Circuitry in stainless steel. • Unit flow regulator device, needle valves and flow stabilizers in stainless steel. • Seat in stainless steel. • Painting with fluidized bed technology RAL 5005. |
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. |
