The inverted pressure balance lubricated plug valve is widely used for cutting and connecting pipeline mediums in various industries such as natural gas, petroleum, chemical, pharmaceutical, fertilizer, electric power, etc.
This kind of plug valve utilizes the structure of completely metal sealed and the advantage of supplying sealant at any time to overcome the demanding applications of natural gas, such as high-pressure difference, throttling, unloading and blowdown, etc, with a working temperature of -29~300℃。
Also, the lubricated valve can be made as DBB, 3-way and 4-ways to meet different application requirements.
