Three-piece Ball valve

Product details: 
Applicable medium: water, solvent, acid, gas, oxygen, hydrogen peroxide, methane and ethylene application: chemical, petrochemical, oil, paper, mining, electricity, gas, food, pharmaceutical, water supply and drainage, municipal, mechanical Equipment Supporting, electronics industry, urban construction and other fields. 
Ball valve and plug valves belong to the same Type of Valve, only its closure member is a Ball, Ball around the body center line rotation to achieve open and close a Valve. Ball valve in the pipeline is mainly used for cutting, distribution Flow direction and changing medium. 
advantage: 
1. Fluid resistance, the pipe resistance coefficient with the same length are equal. 
2. Simple structure, small size, Weight light. 
3. Compact, reliable, current Ball valve face of Seal Materials widely used plastic, Seal is good, it has also been widely used in the vacuum system. 
4. Easy to operate, opening and closing rapidly, from fully open to fully closed as long as the rotation 90 °, to facilitate remote control. 
5. Easy maintenance, simple Ball valve structure, Seal ring generally activities, the removal replacement is more convenient. 
6. In the fully open or fully closed, Seal surface and the dielectric isolation Ball and valve seat, and through the media, will not cause erosion Valve Seal surface. 
7. Wide range of applications, from small to a few millimeters in diameter, large meters, from high vacuum to high pressure can be applied. 
effect: 
Mainly used for switch, cut off or connected line of medium, can be used for fluid regulation and control of. 
Ball valve can be divided according to their channel position Straight through, three-way and straight Angle type. The latter two Ball valve for dispensing media and change the flow of media. 
Installation and maintenance should note the following: 
1. To leave the valve handle rotation position. 
2. not be used as a throttle. 
Ball valve 3. belt transmission mechanism should be installed upright.
