V type ball valve belongs to fixed ball valve, is also a single seat sealed ball valve, regulating performance is the best ball valve, flow characteristics are equal percentage, adjustable ratio of 100:1. it has a shear effect between the V-shaped cut and metal seat, especially suitable for containing fibers, tiny solid particles, slurry, and other media. Ball valve it has the same rotary 90 degrees of action, the difference is that the plug body is a sphere, with a circular through hole or channel through its axis. Ball valve in the pipeline is mainly used to do cut off, distribution and change the direction of flow of media, it only needs to rotate 90 degrees of operation and a very small turning torque can be closed tightly. Ball valves are most suitable for switching, cut-off valve use, but recent developments have been designed to make the ball valve with throttling and flow control, such as V-type ball valves.

Product features

1, the fluid resistance is small, its resistance coefficient is equal to the same length of the pipe section.

2、Simple structure, small size, light weight.

3, tight and reliable, ball valve sealing surface materials widely used plastic, good sealing, in the vacuum system has also been widely used.　

4, easy to operate, open and close quickly, from fully open to fully closed as long as the rotation of 90 °, easy to control from a distance.　

5, easy maintenance, ball valve structure is simple, the sealing ring is generally movable, disassembly and replacement are relatively convenient.　

6, in the fully open or fully closed, the ball and the sealing surface of the valve seat and the media isolation, the media through, will not cause the valve sealing surface erosion.
