Eccentric plug valve: A reliable and durable solution in industrial fluid control
23 Sep, 2026
The eccentric plug valve is a high-performance rotary valve. By simply rotating 90 degrees, it can complete the opening and closing actions. This valve is widely used in industrial fluid control systems. It can precisely regulate the flow of fluid. It can also safely cut off the fluid in the pipeline.
How To Handle Stuffing Box Leakage In a Plug Valve?
14 Sep, 2026
In industrial pipelines such as petroleum, chemical, and heating industries, plug valves are frequently used for media shut-off and control. Stuffing box leakage at the valve stem is a common problem in the field. Workers can usually see liquid seeping between the valve stem and the valve body, or find gas leaking from the stuffing box.
Three-way plug valve: Structure, working principle and industrial applications
09 Sep, 2026
The three-way plug valve is a 90-degree rotary valve. This valve has a valve core with a flow channel, which can control the diversion, mixing and on/off of the fluid in the pipeline. Ordinary two-way valves can only perform simple on/off operations of the pipeline. The three-way plug valve can independently complete the multi-directional switching of the fluid. It can simplify the pipeline layout, reduce the number of supporting equipment, and lower the construction cost of the project. This valve is small in size and runs stably. It can be used in multiple industrial fields such as petrochemicals, oil and gas, energy, water treatment, pharmaceuticals, etc., and is a commonly used fluid control equipment in industrial production.
