Hard Cast Iron Seal Wafer Butterfly Valves-DK56-WB-G
The wafer butterfly valves often just has two or four non-threaded holes to hold it in place and align it with two flanges that are mated. When using a wafer valve, a lengthy bolt or threaded rod that goes straight through the valve’s two flanges is employed. By pulling the flanges together, the valves is held in place. The purpose of a wafer butterfly valves is to maintain a seal to guard against double-directional pressure differential in liquid flow.
Butterfly wafer valves are used in home pipes, firefighting equipment, and ships. These valves are commonly employed in the cooling water system for thermal power plants in addition to other general industries, including petroleum, chemical, gas, and water treatment. Butterfly wafer valves are also appropriate for pressurized applications involving air or gas.
- Model: Butterfly Valve

Description
The butterfly wafer valve is made up of a lot of additional parts. They consist of the body, seal, packing, stem, actuator, and resilient seat. To create the ideal seal, the robust seat is positioned on the valve’s body. In the event that the robust seat is harmed, the packing offers an extra seal.
There are various configurations for industrial butterfly valves. Based on the method, some operate manually while others do it electronically. They come in various styles as well, which can be acquired from an industrial valve supplier. There are some that offer excellent performance in front suctions and huge pump lines.

Advantages Of Wafer Butterfly Valves
Here are the main advantages of butterfly wafer valves:
The flowing medium can travel through a stream-lined butterfly disc without experiencing a significant pressure reduction or flow restriction.
Butterfly wafer valves are quick-acting; to switch the valve from the completely open to the entirely closed position, the stem only needs to be moved 90 degrees (1/4 turn).
The butterfly wafer valve design is well adapted for flow regulation and does not produce much turbulent flow when somewhat opened or shut down.
The butterfly wafer valves are better appropriate for larger applications since they are often less expensive and not heavier.
