How should Sanitary Butterfly Valve be improved?

In some environments, ordinary sanitary butterfly valves can no longer meet the requirements. At this time, the product needs to be improved.

1. The rubber ring is outsourced for production at a fixed point to strengthen quality control. The valves usually used in the water supply industry are made of EPDM rubber and nitrile rubber, but rubber is not used much. It is strictly forbidden to mix rubber. The whole pressure plate of the sealing rubber ring on the butterfly plate is changed to a short dovetail assembly connection to adjust the extrusion degree of the pressure plate in each part to balance the service life of the sanitary butterfly valve, but this adjustment technique is also difficult to master.

2. The sealing rubber ring of the sanitary butterfly valve and the flange sanitary butterfly valve is embedded in the dovetail groove, and there is some activity margin, which can adjust the extrusion condition of the rubber ring when the sanitary butterfly valve is closed.

3. Some companies have introduced a "fluoroplastic" sealing ring to replace the rubber sealing ring to improve the molybdenum resistance and aging resistance of the sealing ring.

4. Many manufacturers have introduced metal-sealed sanitary butterfly valves to replace rubber-ring-sealed sanitary butterfly valves.
