The Operation Theory of Cryogenic Butterfly Valve
The operation theory of a Cryogenic Butterfly Valve revolves around regulating the flow of cryogenic fluids. Unlike a ball valve, which uses a spherical closure, a butterfly valve employs a disc that rotates on a central axis. This rotation controls the flow through the valve. The butterfly wafer valve design ensures a compact profile suitable for tight spaces. With options available in various sizes, including 5 butterfly valve and 1/2 inch butterfly valve, they offer versatility in different applications. When compared to a gate valve, butterfly valves provide quicker operation and require less space.
