Ball valve and plug valve are the same type of valve, but the opening and closing part is a ball with a through hole, which rotates around the center line of the valve stem to achieve the purpose of opening and closing.

Features: the valve has simple structure and reliable operation. It is used for the pipeline of two-way flow medium, with small fluid resistance and good sealing.
Disadvantages:
The medium is easy to leak from the valve stem.
Precautions for use:
a) Same as plug valve;
b) The valve with handle is closed when the handle is perpendicular to the medium flow direction, and open when the handle is consistent with the direction;
c) If the ball valve with jacket insulation is encountered, the following matters shall be paid attention to:
I. The jacket insulation steam shall be opened to melt the medium easy to crystallize in the valve before opening and closing the valve
Do not forcibly open or close the valve before the medium is completely melted
II. When the valve cannot be opened, the method of lengthening the force arm cannot be used to forcibly open the valve,
Because this will cause the valve stem to suffer great resistance and the valve core to fall off, resulting in valve damage or wrench damage, resulting in unsafe factors.
