Universal Wafer Butterfly Valve, compliant with JIS, JPI, API, ASME, EN, ISO and many other pressure standards, easy to connect and adaptable, reducing purchase variety and inventory.
The butterfly valve seat is made of imported rubber with 50% rubber content. The valve seal is reliable, the opening and closing torque is stable, the service life of the valve seat is long, the opening and closing times can be more than 10000 times.
The valve shaft and valve body are equipped with 4 oil-free bearings and 3 o-type seals. The valve shaft supports more vigorously and the axial seal is more reliable.
Ultrasonic cleaning is carried out before packing to prevent contaminants and particulate impurities from remaining in the valve body, to ensure the cleanliness of the valve and to prevent the valve itself from polluting the water body of the pipeline.
The valve body is sprayed with the world-renowned Akzo epoxy resin plastic powder, which can be deposited thicker and has stronger adhesion after the melt is cured.
