The lubricated plug valve adopt the forced lubrication, Use the grease gun injected greased into the oil groove of the body and plug,and this make the seal of the body and plug have a oil film to improve the sealing performance,and it also can save the force when open and close the plug valve,also can prevent the sealing face from damage.
The kind of the grease, it depend on the properties and temperature of the medium.
The pressure of the lubricated plug valve is Class 150-Class 300.
Size from DN15-DN300, the lubricated plug valves are widely used in the oil and gas transmission pipeline,because this kind of pipe will not clean the pipe,and the medium will be included the water and sand,then the lubricated plug valve is the most suitable valve for this application.
