Stainless steel ball valve type Q11F

One-piece ball valve and the flange valve is the same type of valve, the difference in its closure is a sphere, the ball around the centerline of the valve for rotation to open, close a valve. Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of flow of media.

 A, one-piece ball valve has the following advantages:

1. The fluid resistance is small, the resistance coefficient and the same length of the pipe section equal.

2. Simple structure, small size, light weight.

3. Tight and reliable, the ball valve sealing surface material widely used plastic, sealing, and in the vacuum system has also been widely used.

4. Easy to operate, open and close quickly, from full open to fully closed as long as the rotation 90 °, easy remote control.

5. Easy maintenance, simple ball valve, seals are generally activities, the removal replacement is more convenient.

6. In the fully open or fully closed, the ball and seat sealing surface and medium isolation, the media through, it will not cause corrosion of the valve sealing 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.

B, a piece of ball valve position can be divided into its straight-through, three-piece ball valve and right-angle type. The latter two ball valves are used to dispense media and change the flow direction of the media. Wide ball valve installation and maintenance should note the following:

1. To retain the rotation of the valve handle position.

2. Can not be used for throttling.

3 ball valve with transmission should be installed upright.

C, Guangzhou-style ball valve works by rotating the valve to make the valve open or closed. Ball valve switch light, small size, can be made of large diameter, reliable sealing, simple structure, easy maintenance, sealing surface and spherical surface is often closed, not easily eroded by the media in various industries to be widely used.

D, a ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of flow of media. Ball valve is widely used in recent years, a new type of valve, which has the following advantages:

1. The fluid resistance is small, the resistance coefficient and the same length of the pipe section equal.

2. Simple structure, small size, light weight.

3. Tight and reliable, the ball valve sealing surface material widely used plastic, sealing, and in the vacuum system has also been widely used.

4. Easy to operate, open and close quickly, from full open to fully closed as long as the rotation 90 °, easy remote control.

5. Easy maintenance, simple ball valve, seals are generally activities, the removal replacement is more convenient.

6. In the fully open or fully closed, the ball and seat sealing surface and medium isolation, the media through, it will not cause corrosion of the valve sealing 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. Rotate the ball 90 degrees, in the inlet and outlet should be presented all spherical, and thus cut off the flow.

One-piece ball valve is a relatively new type of ball valve, it has its own structure unique to some of the advantages, such as no friction switch, seal is not easy to wear, opening and closing torque is small. This reduces the size of the actuators to be used. Coupled with multi-turn electric actuator can be achieved on the media regulation and tight cut off. Widely used in petroleum, chemical and other urban water supply and drainage requirements of the strict cut off the conditions.
