Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.
The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.
The manual valve is a valve operated by the handle and the hand wheel, and is a commonly used valve on the equipment pipeline.
Valves are the most common equipment in chemical companies. It seems easy to install valves, but if they are not implemented in accordance with the re...

MINOTAUR series replaceable seat high performance butterfly valve
The replacement steps are as follows: 1. If the butterfly valve has been energized and running, the butterfly disc can be opened to the fully open (90°) position by electric or manual methods, then the main power supply is turned off, and a special person will be guarded to ensure that the butterfly valve will not be started by mistake.
2. Use paint or charcoal to make a position mark on the butterfly disc and the sealing ring pressure plate, so that after changing the ring, it can be assembled according to this position.
3. Using an Allen key, unscrew all the countersunk Allen screws on the pressure plate of the sealing ring and place them in a suitable container to avoid loss. Because the sealing ring pressure plate of the large-diameter butterfly valve is relatively heavy, improper operation may cause personal injury or component damage. Therefore, when removing the screws, first remove the two screws on both sides of the butterfly disc at the farthest end of the valve shaft, and then replace them with two M12 bolts with a length of 150-200 to avoid sudden drop of the seal ring pressure plate. After the two long bolts are tightened, all the remaining screws can be unscrewed to ensure safety.
4. At the same time, two people use a flat wedge-shaped steel rod with a head at a symmetrical position of the butterfly disc, insert it between the sealing ring and the sealing ring pressing plate, and pry, and gradually extend the prying position, so that the entire sealing ring pressing plate is separated from the butterfly disc On the positioning stop. Hang on the two bolts that were previously replaced. If there is space to replace the seal ring, it is not necessary to completely remove and lift the seal ring pressing plate. If the site space is too small for replacement, first use a cloth rope to lift the seal ring, and then remove the two long bolts .
5. Remove the old sealing rubber ring on the butterfly disc and replace it with a new one.
6. Reinstall the sealing ring pressure plate on the butterfly plate according to the marked marks, and tighten all the original countersunk hexagon socket screws.
7. Carefully check whether the seal ring and pressure plate are uniform and appropriate. Then clean up the tools and accessories to ensure that no debris is left in the pipeline.
