KONOTOP VALVES PLANT

SHUTOFF VALVE PN 10, 16, 40

Intended to shutoff pipeline once or repeatedly. To be installed at pipelines carrying liquid and gaseous media that are neutral to the materials of body parts.

Body parts are fabricated from the following materials: carbon steel and stainless steels.

Working fluid temperature range: -40 to +200оС

End connections may be both flanged with oval cross-sectioned ring gaskets and welded.

To be supplied to regions with temperate, cold and tropical climate.

Features and advantages

  • Body and flanges are die-forged to ensure their structural strength, and durability..
  • The areas of valve body and stem that provide shutting off are hardfaced with corrosion resistant and high strength alloys and then ground in to contribute to more pressure integrity and tightness and longer lifetime.
  • Packing stem set consists of self-sealing fluoroplastic packing rings that offer perfect tightness and low friction coefficient.
  • Mounting and overall dimensions as well as weight see in the Table.
