Butterfly Valves

Butterfly valves are a family of quarter-turn rotational motion valves that are used in pipelines to shut-off flow. It is often said that butterfly valves can be used to regulate the flow. However, we do not recommend doing this, as it can damage the valve disk and have a negative effect on the sealing properties. They are used in a wide variety of process media and industries especially in water supply, collection, and distribution, as well as pumping stations, and have a broad range of use cases especially in flow isolation. A couple of their key advantages over other valve families are their simple construction and compactness, resulting in the end products being of lighter weights and lower cost and with smaller installation footprints and faster actuation speeds.

Centric butterfly valves with fixed liner feature an outstanding seating concept. The rubber is injection moulded directly on the valve body forming a permanent bond. Consequently, there is no risk of deformation or dislocation of the liner making the valves suitable under vacuum conditions. The combination of the profiled disc edge and the excellent rubber quality ensures maximum durability of the liner.

FEP ptfe coated Butterfly Control Valve and pfa coated Lug Type Butterfly Valve manufacturer in India

PTFE Butterfly Valve is a type of gate valve that has the gate in a butterfly shape and the interior of the valve is coated with a ptfe polymer. The ptfe coated butterfly valve has a body, a stem, a handle and the butterfly disc inside the body of the valve. The disc is connected to a central axis which connects to the stem and handle above. The shape of the disc looks like a butterfly; hence the naming. The ptfe seal butterfly valve operates by opening and closing the valve as the disc is rotated horizontally inside the body. When the dis is in parallel to the pipeline the valve is open and when the disc is in perpendicular to the axis of flow, the valve is closed.

A Pneumatic Double Eccentric Wafer Type Butterfly Valve is a high-performance quarter-turn valve designed for reliable on/off and throttling control. The double eccentric (double offset) disc design minimizes seat friction during operation, resulting in reduced wear, lower operating torque, and extended service life. The valve is actuated by a pneumatic actuator, making it suitable for automated process control in demanding industrial applications.

• Double eccentric (double offset) disc design for longer seat life
• Wafer type body for compact installation between flanges
• Pneumatic actuator for fast and reliable automation
• Low operating torque with bubble-tight shut-off
• Available in double-acting or spring-return actuator configurations
