303 Series Pneumatic Inclined Plate Butterfly Valve

Advantages 

1. Patented inclined plate structural design. When the valve is opened, the butterfly plate is completely disengaged from the valve seat,  resulting in little wear on the butterfly plate seal. 

2. Vulcanized sealing to prevent tearing and scraping. 

3. Progressive sealing structure and streamlined design of the valve body's sealing surface. 

4. The plate-rod is designed without a pin connection, making valve maintenance more convenient. 

5. The streamlined design of the valve body enables internal polishing with no residue.
