In addition, some enterprises may wonder why the anti blocking effect of the angle valve is better than that of the general pneumatic ball valve, mainly because the structure and use of this equipment are designed to meet the production needs. The general pneumatic ball valve is more suitable for the production needs of small enterprises, and this angle travel valve is used for long-term operation and production, And some internal processing systems can clean the impurities inside the equipment.

Variable eccentric butterfly valve: The unique feature of variable eccentric butterfly valve is that the valve stem shaft for installing the butterfly plate is a three-stage axial structure. The two shaft sections of the three-stage axial valve stem are concentric, and the center line of the central section shaft deviates from the axis at both ends by a center distance. The butterfly plate is installed on the intermediate shaft section. Such eccentric structure makes the butterfly plate become double eccentric when it is in the fully open position, and become single eccentric when it is turned to the closed position. Due to the action of the eccentric shaft, when closing, the butterfly plate moves a distance to the sealing cone of the valve seat, and the butterfly plate matches the sealing surface of the valve seat to achieve reliable sealing performance.
