As modern production and life have a large demand for valves, the research on valve technology has also become a national key research project. In fact, in recent years, the research on valves has really achieved a lot. From the beginning of the ordinary plug valve to now, it has entered the field of automation, as well as electro pneumatic and many other categories. 　　

Comparison of performance between V-ball valve and single seat regulating valve V-ball valve is receiving more and more attention in the field of industrial automatic control because of its good regulating performance and cutting off performance. In many applications of single seat regulating valve, V-ball valve tends to replace it. The advantages of V-ball valve over single seat regulating valve are as follows:
1、 The V-ball valve with the same caliber is smaller in size and weight than the single seat regulating valve, and has a higher cost performance ratio. For users with limited budget who want to use the regulating valve, it can save a lot of costs. For occasions with limited installation space, the V-ball valve shows greater advantages than the single seat regulating valve.
2、 Although the leakage of single seat regulating valve is relatively small, it can not achieve zero leakage, which can not meet the requirements for the working conditions with strict leakage requirements, while the V-type ball valve can achieve zero leakage. This can not only meet the regulation performance requirements of the regulating valve, but also meet the cut-off requirements of the shut-off valve.
3、 The ball of the V-shaped ball valve has the shearing function, which is a good choice for the medium containing particles. During the rotation of the ball, the wiping effect will be produced, which can ensure that the sealing surface will never accumulate media. In the paper mill pulp conveying process, the V-shaped ball valve is a necessary choice.
