What are the advantages of sanitary pneumatic ball valves compared to other valves?
Zhejiang Weiheng Fluid Equipment Co., Ltd. is a company specializing in the production of sanitary ball valves. It has many years of experience in the field of ball valves. What are the advantages of pneumatic ball valves compared to other valves? Zhejiang Weiheng Fluid Equipment Co., Ltd. gives you a few points to summarize:
1. Anti-static function: a spring is arranged between the ball, the valve stem and the valve body, which can discharge the static electricity generated by the switching process;
2. 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 damaged, and the sealing capacity increases as the pressure of the medium increases;
3, the valve seat sealing performance is good, the sealing ring made of elastic material such as PTFE (polytetrafluoroethylene), the structure is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of the medium pressure;
4. The thrust bearing reduces the frictional torque of the valve stem, which makes the valve stem smooth and flexible for long-term operation;
5, the fluid resistance is small, the ball valve is the smallest of the fluid resistance of all valves, even the diameter of the ball valve, its fluid resistance is quite small.
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 may be formed between the convex step and the valve body to ensure the valve stem is sealed;
7. The pneumatic ball valve is mainly used to cut off or connect the medium in the pipeline, and can also be used for the adjustment and control of the fluid. Since the material such as PTFE has good self-lubricating property and the friction loss with the sphere is small, the ball valve Long service life;
