Structural Features:

Adopting a three-body symmetrical structure, the valve stem is eccentrically connected to the ball, which overcomes the drawbacks caused by key connection and can effectively transmit torque to the valve ball. A compensation and preloading spring as well as a slag-proof structure are arranged behind the valve seat to prevent the medium from entering the spring cavity and causing spring failure.
