NPT Threaded end lubricated plug valve is can be called as Inverted Pressure balance lubricated plug valve,NPT Threaded end lubricated plug valve can be designed according to ANSI standard, we can customize the inverted pressure balanced lubricated plug valve according to the customer's requirement. NPT Threaded end lubricated plug valve was widely applied for petroleum, chemical industry, pharmacy,chemical fertilizer, power industry etc.1NPT Threaded end lubricated plug valve main application is cutting and connectting the pipeline medium with pressure class 150 to class 900 under the temperature -40℃ to +450℃.
NPT Threaded end lubricated plug valve Main Characteristics
1. There are compact structure, reliable sealing, perfect function and attractive shape for lubricated plug valve natural gas.
2. NPT Threaded end lubricated plug valvee is Inverted pressure balance structure, easy to be opened or closed.
3. There is a oil groove between lubricated plug valve body and sealing surface, the sealing grease can be injected into the seat through glib( oil nozzle) to increase the sealing performance.
4.For the spare parts material and flange size, NPT Threaded end lubricated plug valve can be customized according to different actual working condition to meet project requirements.
