Manual Operation Mode
Product Features
- Small and light for multi-positional installation, easy to be disassembled and maintained
- The structure is simple, compact, and can be open-closed by 90 ° quickly.
- Low torque secured for labor cost saving
- Zero leakage
- Various material available for the use of large variety of medium
- Excellent regulation performance due to straight - lined flow curve
- Long life sue up to tens of thousands of times for open and closing
VII. Operating Principle
- This butterfly valve is mainly composed of valve body, stem, disc and seat, lubrication bushing, pin (can be pin-less design), manual operating device (handle or gear box). The control of medium flow and open and closure are driven and achieved by rotating the stem and the disc.
- For hand lever operation, press the lever and rotate clockwise 90 degrees to close the disc and then release the lever. A targeted regulation and the medium flow will be achieved by locating the position indicator (there are 10 positioning locations between 0 ° ~ 90 °)
- For gear box operation, rotating the worm gear to open and close the disc to achieve targeted medium regulation and flow. The valve will be closed by clockwise rotation
