Butterfly Control Valves

Butterfly valves have been developed for a large number of applications though out process industries.High performance butterfly valves are mainly used for isolation o on-off applications but also suitable for control, especially on high-flow, low pressure applications. t offers additional advantages such as simple structure and low cost.

Performance

  • High Cv to valve weight rato compared to conventional control valves
  • Throttlingcontrols 60° rotation, on-ff controls 90° rotation.
  • Excellent flow control range ability.

Design Flexibility

  • Triple-offset design
  • Metal / Laminated / Softseat available
  • Actuator mounting flange dimensions in accordance with ISO 5211
  • Swing through and tight shut-off seated trim design.
  • Flange types are available
  • Full range of bonnet and packing design to suit various temperatures and fluids
  • Provides fire safe sealing, which combines a soft seal ring and metal seal ring.
  • Full range of body and vane material options. Hard facing available
