1.  Lift Type Plug Valve opening and closing first lift the cock, so that the cock and the seat sealing surface is separated, and then 90° rotation cock, so that the valve open or close. Because the valve in the opening and closing process of the plug and the valve seat is separated, so the valve opening and closing is very easy, and the sealing surface in the opening or closing process is not easy to scratch, the service life of the valve is long.

2. Lift Type Plug Valve whether in the open state or closed state, the sealing surface is protected from media erosion, tight and reliable seal.

3. The ordinary plug valve uses rectangular flow channel, and the flow channel area is reduced, there is a large fluid resistance loss, and the metal hard seal lifting plug valve uses the same circular channel with the cross-sectional area of the pipeline, the fluid resistance is minimal.

4. Lift Type Plug Valve compact structure, small size, compared with the gate valve, the valve height size is greatly reduced, compared with the globe valve, fluid resistance is greatly reduced.

5. Compared with the ordinary plug valve, the metal hard seal lifting plug valve is suitable for a larger range of pressure and temperature.

6. Lift Type Plug Valve on both sides of the seat sealing surface can be sealed, the installation and use of the valve is not limited by the flow direction of the medium.

7. The sealing surface of the seat is raised, easy to clean the sealing surface, the sealing surface is not easy to accumulate crystalline medium or solid particles.

8. Lift Type Plug Valve is closed, the hand wheel and stem can be used to pressure the sealing surface of the valve seat, by increasing the specific sealing pressure, can make the plug valve has better sealing performance.
