An elastic sphere obtains elasticity by opening an elastic groove at the lower end of the inner wall of the sphere. When closing the channel, use the wedge head of the valve rod to expand the ball and compress the valve seat to seal. Loosen the wedge head before rotating the ball, and the ball will return to its original shape, so that there is a small gap between the ball and the valve seat, which can reduce the friction and operating torque of the sealing surface.

When using the electric butterfly valve, you will find that it has good performance under low pressure, which is almost incomparable with other channels. The performance under low pressure can really promote our future use, and the whole product is adjustable, which can really ensure our future use effect. This is a great guarantee for you. We must take this aspect seriously. After all, it will directly affect our future use.
