Lift type hard seat plug valve adopts raising first after the opening and closing of the valve operating mode, which greatly reduce the Lift type hard seat plug valve opening and closing torque.Lift type hard seat plug valve usually adopts the circular channel to make Lift type hard seat plug valve fluid resistance greatly reduced, Lift type hard seat plug valve is applicable to the cutting and connection of pipelines medium that are used in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, power industry etc under nominal pressure of ClASS150-1500lBS,and working temperature of-29-550’C.

Lift type hard seat plug valve Product features:
1 Before Metal seated lift plug valve openand close, it lift the plug first, make the plug and valve seat seal face off, and then 90° turn the plug, make the lift plug valve open or close.Because the Metal seated lift plug valve in the process of opening and closing the plug and valve seat phase off, so the opening and closing of the Lift type hard seat plug valve is very easy, and the sealing surface in the opening or closing process is not easy to scratch, the Lift type hard seat plug valve service life is long.

2  No matter in the open  or closed state, the sealing surface of Lift type hard seat plug valve is protected from medium erosion, sealing tight and reliable.

3 The ordinary plug valve adopts rectangular channel, and the area of the channel is reduced, there is a large loss of fluid resistance, But  the Metal seated lift plug valve adopts the same cross-sectional area of the circular channel to be the minimum fluid resistance.

4 Metal seated lift plug valve has compact structure, small volume, compared with gate valve, the height of the lift plug valve size is greatly reduced, compared with the globe valve, fluid resistance is greatly reduced.

5 Compared with the ordinary plug valve, the Metal seated lift plug valve applicable pressure and temperature range is larger.

6 Metal seated lift plug valve seat sealing surface on both sides can be sealed, the lift plug valve installation and use is not limited by the flow of media.

7 when the Metal seated lift plug valve is closed, it can be through the handwheel and the stem of the valve seat sealing to increase pressure, which can make the plug valve has better sealing performance.

8. The sealing surface of Lift type hard seat plug valve seat is raised to facilitate the cleaning of the sealing surface, and the sealing surface is not easy to store crystalline medium or solid particles.
