Upstream pressure sustaining/relief valve with electrically remote-controlled shut-off fig. XLC 325/425 PN 16/25

The valve maintains the upstream pressure at an adjustable minimum set value regardless of flow variations and, with a solenoid, can open or close in response to a remote command or an external controller.

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

• Control of tank filling with upstream pressure control and opening and closing by electrical signal.

• Flow control through upstream pressure control, with the option of fully closing and opening the valve by electrical signal.

• Located between two pressure zones to protect the low zone from excessive values during off-peak hours and to control the upstream pressure at peak hours, ensuring correct supply to the high zone, with the option of sectioning by electrical signal in the event of an alarm or emergency.
