Technical Specifications
Key Features & Applications
A Pneumatic Triple Offset Butterfly Valve is designed for pipelines where temperature, pressure and sealing performance place greater demands on the valve. Its three-offset disc arrangement allows the sealing surfaces to separate as the valve opens, reducing rubbing and helping protect the seat from premature wear.
Unlike conventional resilient-seated butterfly valves, this design generally uses a metal or laminated sealing arrangement. It is often selected for refinery operations, steam lines, power generation plants and other industrial processes where a suitable metal-seated valve is required.
African Valve manufactures pneumatic triple offset butterfly valves with body materials and pressure classes selected to suit the service conditions. The pneumatic actuator provides remote quarter-turn operation and can be configured with spring return, position indication and other accessories for integration into automated systems.
