Forced lubrication is employed, forming an oil film between the plug and the valve body sealing surface. This provides excellent sealing performance and is widely used in oil and gas pipelines.① It can be opened and closed quickly and easily by rotating 90 degrees.
② It has a bidirectional flow path, fewer parts, light weight, and low flow resistance.
③ The plug valve is suitable for multi-channel structures. One valve can provide the flow path of two, three, or even more valves, simplifying pipeline system design.
④ It is suitable for media with low temperature and high viscosity.
