Upstream pressure support or overflow hydrovalve and block with electric remote control figure XLC 325/425 PN 16/25

The CSA XLC 325/425 automatic valve sustains, installed on the main pipeline, or overflows, installed in the bypass, the upstream pressure regardless of flow rate changes; the set-point value is adjustable. In addition, with the help of a solenoid valve, opening or closing can be accomplished by a CSA control unit or remote pulses. Should the upstream pressure fall below the set-point value, the valve will move to the fully closed position ensuring operation even under static conditions.

Features

– Body and cap of GJS 450-10 ductile iron.

– Internal components of GJS 450-10 ductile iron and stainless steel.

– Position indicator of stainless steel.

– Control circuit of stainless steel.

– Control unit, needle valves and flow stabilizers of stainless steel.

– Blue RAL 5005 epoxy paint applied to fluidized bed.

Applications

– Regulating the level of a tank with a closing impulse connected to the level probe.

– Regulating the flow rate, acting on the preset and adjustable upstream pressure, with the possibility of closing or opening in emergency from remote control in case of alarm.

– Feeding a system by the surpluses of the upstream pressure with the possibility of interception by impulse to the solenoid valve. Reference standards and flanges
