Which is the different for ball valves and plug valves

Plug shape for plug valves can be cylindrical or conical. Plug Valves most suitable for cutting off and switching on the medium and shunt, according to the nature of applicable, sometimes also used for throttling. Another important feature of the plug valve, it is easy to adapt to multi-channel structure, so that a valve can get two, three, or even four different flow channels. This simplifies the design of the piping system, reduces the amount of valve used, and some connecting fittings needed in the equipment.

Plug valves are widely used in oil production, transportation and refining equipment, but also widely used in petroleum, chemical, chemical, gas, liquefied petroleum gas, HVAC and general industries.

Ball valve is mainly used to cut off or connect the pipeline medium, can also be used for fluid regulation and control. This kind of valve should be installed horizontally in the pipeline. The main features of the valve itself is compact in structure, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, widely used in various industries. Ball valve body can be integrated, or can be combination.
