Stainless Steel Plug Valve

Product introduction:

A plug valve is a valve that uses a plug body with a through hole as an opening and closing member. The plug body rotates with the valve stem to realize the opening and closing action. Since the movement between the sealing surfaces of the plug valve has a wiping effect, it can completely prevent contact with the flowing medium when it is fully opened, so it can usually also be used for medium with suspended particles.

Another important feature of the plug valve is that it is easy to adapt to the multi-channel configuration, so that one valve can obtain two, three, or even four different flow channels. This simplifies the design of the piping system, reduces the amount of valves, and some connection fittings required in the equipment.

In order to expand the application range of plug valves, many new structures have been developed. Oil lubricated plug valves are the most important one. Special grease is injected from the top of the plug body between the taper hole of the valve body and the plug body to form an oil film to reduce the opening and closing torque and improve the sealing performance and service life.


1. The plug valve is used for frequent operation, and it opens and closes quickly and easily.

2. The fluid resistance of the plug valve is small.

3. The plug valve is simple in structure, relatively small in size, light in weight, and easy to maintain.

4. Good sealing performance

5. Not limited by the installation direction, the flow direction of the medium can be arbitrary.

6. No vibration and low noise.
