The major feature of NEWLOTOKE’s triple offset metal to metal butterfly valve is that the sealing structure is fundamentally changed through the sealing angle design. It does not rely on the elastic deformation of the valve seat, but completely relies on the contact surface pressure of the valve seat to achieve the sealing. In this way, zero leakage and Bi-direction tightness are achieved.
In response to the needs of different working conditions, we have developed a quintuple eccentric metal to metal bi-direction butterfly valve on the basis of triple eccentricity. It can be used in extreme working conditions such as ultra-high temperature, high pressure, and ultra-low temperature. It is our patented product. Its design is advanced in the world.
