Ball valve

Concepts:
Ball valve with circular vias for opening and closing pieces, turning ball with stem, in order to achieve the opening and closing movement of the valve.

working principle of ball valve:
By rotating the valve stem to keep the valve open or closed.

Feature of ball valve:
1.Ball valve flow resistance is small, ball valves in the flow of all kind of least resistance, even if reduced diameter valve, its flow resistance is quite small.
2.Ball valve switch quickly and easily, as long as the stem is rotated 90 degrees, the ball valve is fully open or fully closed to complete the action, it is easy to open and close fast.
3.The sealing performance of ball valve is good, ball valve seat ring generally use PTFE and other flexible materials, easy to ensure sealing.
4.The stem seal of ball valve is reliable only when the ball starts stem rotates, so the stem seal packing (or O-ring) can not easily be destroyed.
5.Ball valve is simple,the ball valve start just rotated 90 degrees, so it is easy to achieve automatic control and remote control.
6.Ball valve channel is smooth,the ball valve is not easy to have the sedimentary medium, you can pipe through ball.
7.Ball valve have simple structure and easy maintenance.

Classification of ball valve:
Ball valve position can be classified according to their straight-channel, three-way and a right angle. After two ball valves for dispensing media and change the flow of the medium.

The installation and maintenance items of ball valve should note:
1. To leave the rotational position of the valve stem.
2. Ball valve can not be used as throttling.
3. belt drive mechanism should be installed upright.
