Which is the different for ball valves and plug valves

Plug shape for plug valves can be cylindrical and conical. Plug Valves are 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 easily adaptable to a multi-channel design,allowing one valve to get two,three or even four different flow channels.This simplifies the design of the piping system, reduces the use of valves, and some of the connections 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 and connect the pipeline medium.Ball valve can be also used for fluid regulation and control. This kind of valve should be installed horizontally in the pipeline. The main feature of the valve  is compact in structure, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state.The media can not eroded easily , and can not be 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 integration and combination.
