Metal Seal Quadruple Offset Butterfly Valve

Quadruple Offset Design:

Offset 1- axial eccentricity: the rotation center of the valve deviates from the contact plane with the sealing surface.

Offset 2- radial eccentricity: the center of rotation of the valve and the center of the pipeline are not in the same center line.

Offset 3- angular eccentricity: the center of the valve sealing surface forms an angle with the center of the pipeline.

Offset 4- Angle eccentricity: The meshing line on the short side of the sealing surface forms an angle with the center line of the runner.

Main Features:

1.Quadruple eccentric cam design for sealing zero leakage.

2.Bi-directional flowing medium & High-quality sealing effect.

3.Designed in strict accordance with API609 standard. Self-alignment for deformation by different working conditions.

4.According to the requirements of working conditions, the valve seat and sealing ring can produce extremely high hardness and corrosion resistance, with the advantages of erosion resistance, wear resistance, high temperature and high-pressure resistance, long service life, etc.

5.Replaceable sealing pair for maintenance.

6.Small fluid resistance, small installation dimension, small opening/closing torque.

7.Range of working temperature: -45℃~538℃, valve body/disc material such as CS/SS304/SS316/AS can be chosen according to working condition.

8.Connecting type: Flange, BW, Threaded connection.

9.Application: Petroleum and petrochemical, metallurgy, chemical industry, electric power, gas, water conservancy, municipal administration, and construction industries, etc.
