Features and benefits:
1.Bi-directional Seal,metal to metal seat.
2.Open/Close of valve is carried out while the plug and seat separeted,so it will not cause abrasion on the sealing surface.
3.Seat sealing surface protruding, easy to clean sealing surface, sealing surface is not easy to accumulate crystalline medium, or solid particles.
4.It is pressurized for the sealing surface of the seat through the handwheel and stem when valve is closed, which can make the plug valve have better sealing performance.
5.The valve adopts the circular passage with the same cross-section as the pipleline,so the fluid resistance is minimized.
6.Compared with common plug valve,Hard seal lifting plug valves have a wider rang of pressure and temperature.
