An oil groove is arranged between the valve body and the sealing surface of the lubricated plug valves, and the sealing grease can be injected into the valve seat through the grease nozzle at any time to increase the sealing performance. The material and flange size of the parts can be reasonably matched according to the actual working conditions or user requirements to meet various engineering needs.
The oil-sealed plug valve is suitable for the pipelines of various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and electric power industries with a nominal pressure of CLASS150-CLASS1500 and an operating temperature of -29-180 °C.
