Metal seated lubricated plug valve can be designed according to ANSI standard, and metal seated lubricated plug valve was widely applied for petroleum, chemical industry, pharmacy, chemical fertilizer, power industry etc. Lubricated plug valve can be called as Pressure balance lubricated plug valve, and the main application of Metal seated lubricated plug valve is cutting and connecting the pipeline medium with pressure class 150 to class 2500 LB under the temperature -29℃ to +180℃ or -40℃~450℃.

Metal Seated Lubricated Plug Valve - Main Characteristics

1. There are compact structure, reliable sealing, perfect function and attractive shape for lubricated plug valve natural gas.
2. Metal seated lubricated plug valve 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, metal seated lubricated plug valve can be customized according to different actual working condition to meet project requirements.

Venturi Pattern: The plug port is reduced area, but the change of section thru the body throat is so designed as to produce a Venturi effect to restore the velocity head losses thru the valve thus resulting in a relatively low pressure drop. 
Regular Pattern: These valves have face to face dimensions in accordance with the appropriate British and American standards where applicable. This ensures the maximum interchangeability between valves or different types and end connections. The plug ports of these valves have a rectangular-slightly tapered shape in section and have an area larger than Venturi Pattern. The transition from the round body end ports to the rectangular seat ports is smooth, and entails no sudden alteration in shape or section which might cause excessive changes in velocity or direction of the fluid flowing in the pipeline. 
Short Pattern: These valves have the same face to face dimension as gate valves according to ANSI B16.10 in class 125,150,250 and 300. In order to obtain the relatively short face to face dimensions, the plug port is reduced and has a rectangular slightly tapered-shape.
