Automatic piezometric level control valve fig. XLC 370/470 PN 16/25

The XLC 370/470 valve, installed at the base of the elevated tank from which it takes pressure to detect the piezometric level, gradually closes the supply when the preset maximum level is reached, and opens again when the level starts to fall.

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

• Highly sensitive level control in elevated tanks, proportional to consumption and with no need to install equipment in the tank. Can be used for tail-end tanks.

• Flow modulation in response to static pressure measured by the highly sensitive proportional pilot.

• Designed and tested to EN 1074.

• Flanges from DN 50 to DN 800 mm, larger sizes on request.

• Flanges to EN 1092/2, others on request.

Working conditions

• Pressures: 10-16-25 bar.
