Flow limiting and pressure reducing valve fig. XLC 331/431 PN 25

The CSA XLC 331/431 control valve reduces the downstream pressure regardless of upstream pressure variations and at the same time limits the maximum flow to a set value.

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 the main discharge line, to protect against excess flow and pressure.

• For pressure reduction in plants and installations and as protection against excessive flow at peak hours and possible pipe bursts.

• Stabilising water consumption and pressure fluctuations in secondary lines during changes in fluid parameters caused by regulation and control operations.

Reference standards and flanges

• Designed and tested to EN 1074.

• Flanges from DN 50 to DN 400 mm, larger sizes on request.

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

Working conditions

• Pressures: 10-16-25 bar.

• Minimum pilot pressure: 1.5 bar.

• Clean water up to 70ºC, version for higher temperatures on request.
