Offset butterfly valves are a kind of valve used in controlling the flow of gases or fluids. In these valves, the disc is not located at the center but is rather slightly off the centerline. This design is beneficial for the improvement of the sealing performance and it also reduces wear over time. Such valves find their usage in various industrial applications like water treatment, chemical processing, and oil refining. They are known for their reliable shut-off performance, especially with viscous or sticky fluids.
Difference Between the Offset and Double Eccentric Butterfly Valves
Considering the fact that both offset and double eccentric butterfly valves are meant to ensure better sealing and long life yet they differ in structure.
Offset butterfly valves are the ones whose axis is off the center of the disc. This allows the disc to rise slightly off the seat during operation, thus, decreasing friction of the wear process.
Double eccentric butterfly valves adopt the same concept but to a greater extent by making two offsets, the shaft and the disc. Thus, the disc and the seat will have even less contact, which makes the product suitable for high-pressure and high-temperature applications.
Both types ensure top-rated sealing, however, double eccentric butterfly valves are more preferable for heavy-duty tasks like power plants and the heavy industry.
Choosing the Proper Offset Butterfly Valve Size
When one wants to buy an offset butterfly valve, it is highly recommended to acknowledge the next points:
Material: Select cast iron or ductile iron as per the specifications of your project.
Sizes: DN40 to DN1200 (2 to 48 inches) are normal sizes. When it comes to major projects, make sure to pick the DN800 valve type which gives the best flow control.
Pressure Rating: The flange standard you must hunt for is PN10/16 or Class 150 so that the valve stays compatible with your system.
Temperature Range: To deal with the temperature experienced during the normal working conditions, the valve must be capable of functioning from -40°C to 120°C.
Shutoff Performance: Sealed by force designs, especially for the case of sticky or viscous fluids, have a higher degree of tightness.
Check also that the valve adheres to various international quality standards such as CE certification. Long-lasting reliability is only possible through secure high-quality manufacturing and testing processes.
