Lubricated Plug Valves Collection

A cavity in the middle of our lubricated plug valves contains a sealant that moves toward the radial holes, creating a renewable seal between the plug and body when operated. The sealant can also act as a lubricant that reduces friction to elongate the plug valve’s lifespan.

DomBor is a reliable lubricated plug valves manufacturer with its advanced CNC machining equipment that allows for precision manufacturing. Through our extensive QC system, we ensure your lubricated plug valves can achieve superior flow control and have an extended service life.

Highlights

  • Regular, short or venture pattern
  • Full bore or Reduce bore
  • Blowout proof stem
  • The Pressure Balance System
  • One-piece plug

Main Features of the Product

  • It can be used as pigging pipeline trunk isolation valve or pigging receiver / launcher isolation valve.
  • There are four different patterns:
    1.short pattern(rectangular port areas of 40%-60%)
    2.Venturi pattern(rectangular port areas of 40%-50%)
    3.Regular pattern(rectangular port areas of 50%-70%)
    4. full bore(acc to API 6D,use for pigs through the valve)
  • Various kinds of sealant greases are available, including the following models: 7903 (oil-proof sealing grease), 7605 (oil-proof sealing grease), 7602 (high temperature grease stick), 7603 (stem grease stick), which meet different use conditions.
  • Valve stem with multiple seals, Viton + graphite + grease lubrication system, effectively prevent valve leakage
