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
