Analysis On The Advantages Of Holding Ball Valve
- Nov 01, 2017 -

Insulation jacket ball valve is a relatively new type of ball valve, it has its own structure of some of the unique advantages, such as the switch without friction, sealing is not easy to wear, opening and closing torque is small.

This reduces the size of the actuator. With multi-turn electric actuator, can achieve the regulation of the media and tightly cut off. Because of its small fluid resistance, simple structure, close and reliable, easy to operate, easy maintenance of many advantages are widely used in petroleum, chemical, urban water supply and drainage requirements such as strict cut off the conditions.

QB71F on the outside of the valve body with a metal jacket, in the side of the ball valve, the bottom of the jacket with a connection for the steam out of, so as to play on the ball valve insulation effect, to ensure that the sticky Media circulation is normal. The clip-on ballast has the characteristics of compact structure, small volume, light weight, good sealing performance, flexible opening and closing, easy installation and so on.

Insulation jacket ball valve has the following advantages:

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

2. Simple structure, small size, light weight.

3. Close and reliable, the current ball valve sealing material widely used plastic, good sealing, in the vacuum system has also been widely used.

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

5. Easy maintenance, ball valve structure is simple, the seals are generally active, demolition and replacement are more convenient.

6. When fully open or fully closed, the ball and valve seat sealing surface and the media isolation, the media through, will not cause the valve sealing surface erosion.

7. Applicable to a wide range of diameter from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.
