One-piece Ball valve

Product details: 
One-piece Ball valve and Flange Gate Valve is belong to a Type of Valve, the difference between its closure member is a Ball, Ball around the body center line rotation to achieve open, closed structural characteristics of a Valve, One-piece Ball valve in : 
1, open and close without friction This feature completely solve the traditional Valve Seal due to friction between the surface and the impact Seal problems.; 
2, the coat structure of the Valve installed in the pipe-line inspection and maintenance directly, can effectively reduce the plant parking and reduce costs; 
3, a single valve seat Valve design eliminates the abnormal pressure in the cavity due to the media affect the use of safety.; 
4, low-torque design special structural design Valve rod, just with a little hand Valve can easily open and close; 
5. Seal wedge structure. Valve mechanical force is provided by Valve rod, ball wedge pressure to the valve seat and Seal, Seal of so unaffected by pressure changes in the pipeline Valve and Seal performance under various conditions are there are a reliable guarantee; 
6, self-cleaning surface structure Seal When Ball was poured from the valve seat, the fluid in the pipeline along a 360 ° BallSeal surface evenly through not only eliminates the high velocity fluid on the valve seat of local erosion, but also washed away the surface of the Seal accumulations reach self-cleaning purposes. 
product features: 
Nominal pressure: 1.6-6.4MPa 
Applicable stability range: -20 - 232 °C - 350 °C 
Applicable medium: water, oil, gas and some corrosive liquid (WO G) 
Thread Type:... G. NPT BSPT BSP DI259 / 2999 
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. 
One-piece Ball valve can be divided according to their channel position Straight through, Three-piece Ball valve 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.
