The ball valve is mainly used to cut off or turn on the medium in the pipeline, and can also be used for fluid regulation and control. Compared with other valves, it has the following advantages.

1. The fluid resistance is small, and the ball valve is the one with the least fluid resistance in all valves. Even for the reduced diameter ball valve, the fluid resistance is quite small.
2. The thrust bearing reduces the frictional torque of the valve stem, which makes the valve stem smooth and flexible for long-term operation.
3. The sealing performance of the valve seat is good. The sealing ring made of elastic material such as PTFE is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of the medium pressure.
4. The valve stem seal is reliable. Since the valve stem is only used for the imitation rotation and does not perform the lifting movement, the packing seal of the valve stem is not easy to be broken, and the sealing capacity increases as the pressure of the medium increases.
5. Since the material such as polytetrafluoroethylene has good self-lubricating property and the friction loss with the spherical body is small, the service life of the ball valve is long.
6. The bottom mounted valve stem and the stem of the valve stem prevent the valve stem from being sprayed out. If the valve stem seal is broken due to fire, metal contact can be formed between the convex step and the valve body to ensure the valve stem is sealed.
7. Anti-static function: a spring is arranged between the ball, the valve stem and the valve body, and the static electricity generated by the switching process can be derived.

The actuator adopts a new series of GT-type pneumatic actuators, which have double-acting and single-acting (spring return), rack and pinion transmission, safe and reliable; large-diameter valves adopt series AW pneumatic actuator fork-type transmission, and the structure is reasonable. The output torque is large, double acting and single acting.

1. Gear type double piston, large output torque and small volume.
2. The cylinder is made of aluminum and gold materials, which is light in weight and beautiful in appearance.
3. Manual operation mechanism can be installed at the top and bottom.
4. The rack type connection can adjust the opening angle and rated flow.
5. The actuator can be equipped with electric signal feedback indication and various accessories for automatic operation.
6, IS05211 standard connection provides convenience for the installation and replacement of the product.
7. The joint screws adjusted at both ends can make the standard product have an adjustable range of ±4° at 0° and 90°. Ensure synchronization accuracy with the valve.
