Butterfly Valves

When it comes to handling powders in different industries, the Butterfly Valve is used to control the flow of these materials. They are used for managing powder flow in various industrial applications. The valve is named after the wing-like disk that pivots on a central axis, resembling the wings of a butterfly. This unique design enables quick and efficient flow control by rotating the disc parallel or perpendicular to the flow direction.  

Process and Importance:

The working process of C.O.R.A butterfly valves involves a disc-shaped, quarter-turn valve that pivots around a central axis within the pipeline. When the valve is in the closed position, the disc blocks the flow of granules, powder, or dry solids, preventing any material from passing through. To facilitate material flow, the valve can be easily rotated to its open position, allowing for unobstructed passage. What sets C.O.R.A butterfly valves apart is their exceptional sealing performance, which minimizes material leakage and ensures airtight operations. These valves work well for pneumatic conveying systems, as they can handle high-pressure environments while providing precise control over material discharge. Whether it’s in the pharmaceutical, food processing, or chemical industry,  C.O.R.A butterfly valves are essential for ensuring the smooth and efficient handling of materials.

Have any Question?

Can Butterfly Valves be used for both feeding and discharging powders?

Yes, butterfly valves are versatile and can handle both granular and fine powders.

Regular cleaning and selecting the right valve design can prevent powder buildup.

Yes, butterfly valves are adaptable and can handle powders with variable particle sizes.

A butterfly valve uses a rotating disc to regulate flow, while a gate valve uses a sliding gate. Butterfly valves are generally lighter than gate valves.
