FLX-500PV type ball, using the percentage of part V-notch shape sphere specially designed so that it not only has a large adjustable ratio, while also ensuring good adjustability. Because of the spool in the course of action, you can form an effective shear between the V-notch and seat sphere, with six straight-through structure is very suitable for fiber media, slurry, powder and other fluids, gases and control steam. After V-spherical special treatment, can achieve continuous smooth, unimpeded movement, simply by removing the seat and the support ring to check the performance of the valve seal, so that maintenance becomes very fast and easy to grip with the French style Body style blue links in the form of options.
