ANSI Standard High Performance Triple Offset Butterfly Valve For Industry Pipeline Use
Product introduction:
The American standard butterfly valve is a high-performance butterfly valve designed and manufactured according to the current American standard API609. The valve adopts a three-dimensional eccentric conical seat sealing pair, and the butterfly plate seal uses a new type of metal plate embedded on the butterfly plate to match the valve seat. By using the butterfly plate to rotate and compress the seal, the friction resistance of the sealing surface is small, and it has a function of tightening as it closes. This ensures reliable sealing performance, and opening ensures that the seal is completely out of contact, ensuring that the sealing surface is not damaged. API butterfly valves are divided into flange type three eccentric structure, clamp type three eccentric structure, and valve body with protrusions around, designed as a single flange structure with screw holes.

Product features:
1. Simple external structure, small volume, light weight, low cost, and wide application range
2. The structural characteristics of this butterfly valve eliminate the disadvantage of other types of butterfly valves being over opened and unable to seal, and it can be used normally at high temperatures, overcoming the defect of easy leakage due to thermal expansion when used under high temperature conditions.
3. The valve selects different sealing surface materials according to the requirements of the medium used to ensure that the sealing surface is resistant to wear, erosion, and has a long service life.
