Butterfly valves are essential components in the world of flow control. These versatile valves play a crucial role in regulating the flow of fluids in various industries. In this comprehensive guide, we will explore the working principle, types, advantages, and applications of butterfly valves . Understanding Butterfly Valves Butterfly valves are quarter-turn valves that use a circular disc (the "butterfly") with a pivot in the middle. The disc can be rotated to control the flow of fluids through the valve. When the disc is parallel to the flow direction, the valve is fully open, and when it's perpendicular, the valve is fully closed. Types of Butterfly Valves 1. Wafer Style Butterfly Valves Wafer style butterfly valves are lightweight and easy to install between flanges. They are suitable for applications where space is limited, and they offer excellent bi-directional sealing. 2. Lug Style Butterfly Valves Lug style butterfly valves have threaded inserts (lugs) on both s...
