Advantage

1, Three- eccentric structure: When valve is closed more tight , then seal will be more compact.

    Sealing surface is very reliable , and with zero-leakage.

2. Metal seat : Seat is bead welded with hard metal, valve can bear corrosive, high temperature,    abrasion. With long service life.

3. Multilevel hard and soft overlapped seal ring: easy to install, regulate, and replacement.

4. The whole valve adopt steel material, it has a character of fireproof in itself.
