Description

Our double eccentric butterfly valves are designed for superior sealing performance, reduced wear, and extended service life. Featuring an offset disc design, these valves minimize seat contact during operation, resulting in lower torque, less friction, and improved durability in demanding industrial applications.

Size Range: DN50 to DN2400
Pressure Rating: PN10 / PN16

Construction & Materials:

  • Body Materials: Ductile Iron (DI), WCB, CF3, CF3M, CF8, CF8M
  • Disc Materials: DI, WCB, CF3, CF3M, CF8, CF8M
  • Seat Materials: NBR, EPDM, PTFE, Silicone (SI)
  • Stem Materials: 45#, 410, 2Cr13, Cr13, Stainless Steel 304 / 316

Key Features:

  • Double eccentric (double offset) design reduces seat wear and extends valve lifespan
  • Tight shut-off with reliable sealing performance
  • Lower operating torque compared to concentric butterfly valves
  • Suitable for bi-directional flow applications
  • Corrosion-resistant material options for harsh environments
  • Compatible with manual, gearbox, pneumatic, or electric actuators

Applications:

Widely used in water treatment, mining, power generation, HVAC systems, and general industrial pipelines handling water, air, oil, and non-corrosive or mildly corrosive media.
