Product Description :
The plug valve has a simple structure, quick opening and closing, small fluid resistance, and fast angular stroke operation. In emergency situations such as accidents, it can quickly connect or cut off the pipeline. Compared with gate valves and stop valves, it is more flexible to operate and quicker to open and close. The plug valve uses a plug body with a through hole as an opening and closing part, and the plug body rotates with the valve stem to achieve the opening and closing action. Small plug valves without packing are also called """"cocks"""". The plug body of the plug valve is mostly a cone (also a cylinder), which cooperates with the conical hole surface of the valve body to form a sealing surface.

There are many forms of plug valve channels. The common straight-through type is mainly used to cut off fluids. Three-way and four-way plug valves are suitable for fluid reversing. The opening and closing part of the plug valve is a cylinder with a hole, which rotates around the axis perpendicular to the channel to achieve the purpose of opening and closing the channel. The plug valve is mainly used to open and close the pipeline and equipment medium.

Applicable occasions:
Since the closing part of the stainless steel plug valve is a plunger-shaped rotary valve, the channel on the valve plug is combined or separated with the channel on the valve body by rotating 90o to achieve the function of opening and closing the valve, so the plug valve is suitable for occasions of rapid opening and closing; in addition, due to the structural characteristics of the plug valve, it is mainly used for cutting off and connecting the medium and distributing and changing the flow direction of the medium; but according to the applicable properties and the erosion resistance of the sealing surface, it can sometimes be used in throttling occasions; in addition, since the movement between the sealing surfaces of the plug valve has a wiping effect and can completely prevent contact with the flowing medium when fully opened, it can usually be used for media with suspended particles; another important feature of the plug valve is that it is easy to adapt to the multi-channel structure, so that one valve can obtain two, three, or even four different flow channels, which can simplify the design of the pipeline system, replace several valves with one, and reduce the amount of valves and some connecting accessories required in the equipment.

Three-way plug valves are used in the mining, transportation and refining equipment of oil and gas fields; they are also widely used in petrochemical, chemical, natural gas, liquefied petroleum gas, coal gas, HVAC industry, food industry and pharmaceutical industry systems.

Main advantages of plug valve :

1. Suitable for frequent operation, quick and easy opening and closing.
2. Small fluid resistance.
3. Simple structure, relatively small size, light weight and easy maintenance.
4. Good sealing performance
5. Not restricted by the installation direction, the flow direction of the medium can be arbitrary.
6. No vibration and low noise.
