Valve type and principle-Butterfly valve

The valve flap of the butterfly valve rotates around the shaft in the valve seat,the size of the angle of rotation is the degree of opening and closing of the valve.

The butterfly valve has the characteristics of light weight, saves material compared with other valves, has simple structure, quick opening and closing, is suitable for cutting and throttling, has small fluid resistance, and is labor-saving.Because butterfly valves are cheaper than gate valves and have good regulation, butterfly valves are widely used in hot water pipes.The cooling tower is one of them.
