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.

Plug Valve: Principles, Types, Advantages and Applications
14 Aug, 2026
The plug valve is a widely used valve for industrial pipelines. It is primarily used to open and close pipelines and control fluid flow inside pipes. The valve is fitted with a rotatable cylindrical or tapered plug. A through hole runs through the plug, which controls the passage of liquids, gases and slurries. The plug valve boasts a compact structure, low fluid resistance, stable sealing performance and simple routine maintenance. It is extensively adopted across various industrial production lines including petroleum, chemical engineering and natural gas sectors.
