2024-11-04
Ball valves and butterfly valves are common types of valves, and the main difference between them is the structure and working principle.
The opening and closing part of the ball valve is a sphere, which controls the fluid by rotating the sphere, and its sealing surface is spherical. Ball valve switch light, suitable for a variety of media, with excellent sealing and cut-off function. The butterfly valve disc is disc-shaped, by rotating the disc to control the fluid, the sealing surface is flat or conical. Butterfly valve structure is simple, suitable for large flow occasions, has better regulation performance.
In general, the ball valve is more suitable for frequent switching, sealing requirements of the occasion, while the butterfly valve is in large flow, low pressure loss of the occasion performance is better. The choice of valve depends on the specific application requirements and engineering conditions.
