Double chamber upstream pressure sustaining valve fig. XLC 320/420-S-DC PN 25

The CSA XLC 320/420-S-DC control valve is an automatic hydraulic globe type valve that maintains the upstream pressure at an adjustable minimum value regardless of flow variations.

Features

• GJS 450-10 ductile iron body and cover.

• GJS 450-10 ductile iron and stainless steel internal components.

• Stainless steel position indicator.

• Stainless steel pilot circuit.

• Stainless steel adjusting device, needle valves and flow stabilisers.

• Stainless steel seat.

• RAL 5005 blue epoxy coating applied by fluidised bed technology.

Applications

• On pumps, to prevent excessive flow and keep the pump at a working point.

• At tank inlets, to stabilise the flow and the upstream pressure.

• On trunk mains, to prioritise supply to elevated zones when consumption in low zones is high.
