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...

The valve legend (valve graphical symbol) is a graphical representation of the valve in a simple graphic depiction. The valve legend plays a schematic and standard role. In general, the valve legend is not much different, but there will be some regional differences.
The valve legend includes a legend for each type of valve, which also contains symbol information for various commonly used valves such as ball valves, butterfly valves, gate valves, and globe valves. In the professional drawing of water supply and drainage, the valve legend is an important reference.
Different types of valve symbols are different. To help you master the symbolic representation of each valve, the following is a summary of the valve legend for everyone to review.
