ANSI Butterfly Valve

1. Tri-eccentricity structure, butterfly plate and adjusting seat phosphorus are indirectly deficient or separated, truly realizing zero wear and zero leakage.

2. Since the sealing ring is completely embedded in the butterfly plate, the whole regulating valve can be removed without grid during maintenance, which is easy to replace and greatly reduces the maintenance cost.

3. The sealing ring adopts the sealing surface of soft and hard laminated stainless steel sheet and flexible graphite plate (stone egg rubber plate, asbestos rubber plate, etc.), so that it has the double advantages of metal hard sealing and elastic sealing, and has excellent sealing performance no matter under low temperature or high temperature conditions.

4. The sealing surface of the reading seat adopts hardfacing, which makes the sealing surface wear resistant and has a long service life. It can be opened and closed continuously for more than 10000 times without damage.

5. By selecting appropriate materials, the word gate can withstand low (high) temperature and corrosion.

6. As all refractory materials are used, they have reliable fire resistance.

7. The tri-eccentricity structure enables the valve to have a self-locking function. When the butterfly plate is closed to the sealing position, it will immediately realize self-locking, and no fault will occur when the butterfly plate is closed.

8. The valve is easy to operate, with low torque at the output end, streamlined design of butterfly plate, low pressure loss coefficient, and adjustable energy-saving product.

9. The sealing seat can be adjusted, which is conducive to assembly and maintenance. The flow can be closed or adjusted at will.

10. The connection mode between the valve and the pipeline includes flange and clip connection, which can be manual, electric, pneumatic, hydraulic or electric, pneumatic, hydraulic linkage.
