Instructions for use:
When the valve is closed, the V-shaped notch and the valve seat produce a wedge-shaped shear effect, and it has both self-cleaning function and prevents the ball core from getting stuck, especially suitable for pipeline scaling and freezing. It is suitable for controlling pulp, sewage, fiber and particle solid suspension medium and powder particle barrier medium. The ZGH series cylinder piston actuator is equipped with simple structure and large transmission torque. This series of ball valves are divided into soft seal and hard seal according to sealing performance; According to the adjustment mode, it is divided into adjustment type and cutting type, the cutting type is divided into single action type and double action type according to the action type, and the adjustment type is double acting type. The unique advantage of the single-acting type is that once the power source fails, the ball valve will automatically be in the closed and open positions according to the requirements of the control system. The products are widely used in electric power, petroleum, chemical, papermaking, light textile, food, pharmaceutical, aerospace and other fields.
