What matters should pay attention for the ball valve installation and maintenance?

Ball valve has a small fluid resistance, the drag coefficient equal to the same length of the barrel; simple structure, small size, light weight; compact and reliable valve sealing surface material widely used plastic, sealing, and has also been widely used in the vacuum system ; easy to operate, opening and closing rapidly, fully closed as long as the rotation 90 °, easy remote control from fully open to; easy maintenance, simple ball valve, seals are generally activities, the removal replacement is more convenient; in full or When fully closed, the ball and seat sealing surface and the dielectric isolation, through the media, will not cause erosion of the valve sealing surface. Ball valve installation and maintenance should note the following:
1) Ball valve handle rotation to leave the position.
2) Cannot be used as a throttle.
3) Ball valve belt transmission mechanism should be installed upright. Ball valve works by the rotary valve love to make the ball valve flow or occlusion. Ball valve switch light, ball valve small size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, with the spherical sealing surface often in the closed state, the media cannot easily be eroded, in various sectors has been widely used. A ball valve in the pipeline is mainly used for cutting, distribution and changes the direction of media flow. Metal seat ball valve is a relatively new type of ball valve type, it has its own unique structure some advantages, such as switches without friction, seal easy to wear, small opening and closing torque. This reduces the actuator with the specifications. With multi-turn actuators can be realized on media regulation and tight cut. Widely used in urban water supply and drainage in petrochemical demanding cutting conditions.
