Triple Offset Butterfly Valves Collection

With a stainless-steel hardening treatment, our triple-offset butterfly valves (or triple eccentric butterfly valves) come with abrasive resistance to withstand harsh environments. Along with wear and scour resistant seal rings, our valves are made with a one-piece casting craft mold for a more stable structure. A geometric design for sealing components gives our valves friction-free stroking to extend their service life.

DomBor Valve meets high demand for its valves with lean production practices and the efficiency of our lathes, CNC machines, machining centers and other machines. Applying the latest technology throughout production results in accurate valve designs that directly respond to your concerns.

Highlights

  • Laminated resilient disc seal
  • Lower torques
  • Zero leakage seat tightness
  • Fire safe design
  • Fugitive Emissions
  • Live-loading of packing
  • Industry-leading emission control
  • Metal & Graphite Laminated Disc Sealing

Main Features of the Product

  • The replaceable seat and seal ring system extends the overall service life of each Dongbao valve, thus minimizing downtime without expensive field maintenance or full replacement
  • Two way zero leakage seal
  • The unique three eccentric structure makes our valve stable, reliable and easy to maintain
  • Compared with gate, stop or ball valves of the same size and pressure class, Dongbao butterfly valve saves space and weight, and reduces the installation and maintenance cost to the greatest extent.
  • High strength material stem, anti fly out stem and integrated stem design make the valve more stable and suitable for more operation modes
  • Live-loading of packing and low leakage packing (meet ISO 15848-1) makes the stem seal safer and suitable for more working conditions
