Pneumatic Ball Valve Pneumatic ball valve is a kind of valve which is equipped with pneumatic actuator. The execution speed of pneumatic actuator is relatively fast, the fastest switching speed is 0.05 second/time, so it is also called pneumatic fast cut off ball valve. Pneumatic ball valves are usually equipped with a variety of accessories, such as solenoid valve, F.R.L, limit switch, locator, control box, etc. The advantages of pneumatic ball valve in the pipeline are on the below:

DYE penetrant inspection (DPI), also called liquid penetrant inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). LPI is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.
Gate valve means stem nut on the bonnet or bracket, the opening and closing of the brake plate is to use rotary stem nut to achieve the valve stem lifting. This structure is advantageous to the lubrication of the stem, and the opening and closing degree is obvious, so it is widely used. Usually on the lifting rod with trapezoidal screw threads, through the valve top of the nut and the guides lot on the rotating movement into a straight-line ,that is, the operation torque into operation Thrust.
