Vahn-Tech Lubricated Taper Plug Valves are suitable for use in pipelines with various kinds of working conditions, such as nominal pressure of Class 150 to Class 300 and an operating temperature of -25˚C to +325˚C within the following industries: petrochemical, chemical pharmaceutical, fertilizer and power plant, etc., to cut off or turn on the flow medium in pipelines.
Vahn-Tech has adopted a grease-sealed structure for the valve body's outlet, a convenient feature for pipelines with grain slurry medium. There is a grease chimb in the plug surface, where the grease gets in with higher pressure than the slurry in pipelines; thus, forming an oil film to isolate slurry with the plug of rest state from getting into the gap between the valve core and valve wall, which avoids rubbing. High-speed oil flow is generated under the plug’s dynamic state to impact slurry and prevent it from entering the gap, ensuring the normal operation of plug valves, and further enhancing the economic functions of slurry pipeline transportation engineering.
