What is a butterfly valve?

butterfly valve is a type of flow control device that uses a rotating disc to regulate the flow of a fluid. The disc is positioned in the center of the pipe and operates similarly to a butterfly's wings, hence the name.

How does a butterfly valve work?

When the valve is closed, the disc blocks the pipe completely. When the valve is fully open, the disc is rotated a quarter turn to allow an almost unrestricted flow. Partially opening the valve allows for throttling the flow.

What materials are used to make butterfly valves?

Butterfly valves can be made from a variety of materials, including cast iron, stainless steel, plastic, and other materials depending on the application and the fluids being handled.

Pneumatic Butterfly Valves in India

Pneumatic Butterfly Valves

India Pneumatic Butterfly Valves are generally known as a industrial automation system used in the control and regulation of the flow of liquids, gases, and slurries. Pneumatic actuator is a system that operates these valves and the actuator operates the valve efficiently by using compressed air. Pneumatic butterfly valves are characterized by rapid working, small size, and standard functioning, which is why they became the most appropriate solution in the industrial context nowadays.

Pneumatic butterfly valves are widely applied in chemical processing, water treatment, pharmaceuticals, food processing, and power plants as well as oil and gas industries in India. They are an ideal choice in automated flow control systems because of their lightweight nature, low maintenance needs and their affordability in terms of performance.
