Knowing why you need to size a pneumatic butterfly valve on an industrial pipeline, can make the difference when it comes to providing optimal performance and improving flow control. Summary: Mainly used in industrial pipelines to regulate the flow of liquids or gases, a pneumatic butterfly valve is a device that has a disk rotating to open and close for controlling the passage of materials. The size of a pneumatic butterfly valve is an important factor to consider when trying to meet the needs of a particular application and control flow effectively.
Size of a pneumatic butterfly valve
When choosing the size of a pneumatic butterfly valve, according to the media flow rate of the pipeline interface diameter and the material with characteristics such as temperature and pressure. Select the appropriate size for the worst flow rate and pressure in which the system is operating so that it will operate effectively and smoothly. Large Pneumatic Valves may result in high pressure drop and low performance, while too-small may have a risk of flow restriction.
Industrial pneumatic butterfly valves must be sized matching the flow coefficient (Cv) and the pressure drop across valve sizing recommendations
This so called Cv value is a flow capacity of the valve and determined by the valve diameter, disc design. Greater Cv values are indicative of higher flow capacity, and lower Cv values are indicative of a lower flow capacity. The butterfly valves should be selected with a Cv value that allows for correct flow control and proper operation.
If done wrong, it can have serious ramifications on the functioning and efficiency of industrial pipelines. If the valve is too small, it cannot pass the maximum flow rate of your system creating flow restrictions and pressure build up as a result. It will result in inefficiencies, decreased system performance, and may damage equipment. To the contrary, a valve that is too large might create too great of pressure drops and require more power than needed to achieve its goals in which case this costs can be translated as poor cloud performance and operational inefficiency. Sizing the valves correctly, is thus important as this arguably helps in ensuring its optimum performance besides keeping industrial pipelines free of expensive troubles.
Steps to properly size a pneumatic butterfly valve
Some steps to properly size a pneumatic butterfly valve for precision flow control in industrial applications. Are as follow; Think with an engineer or pneumatic butterfly valve expert, Squeeze the application, Perform detailed calculations and analysis for determining the correct value size. Selecting the proper valve size for a system is not as easy as looking at a chart and matching the pipe, however, there are other factors to consider when sizing a valve; flow rate, pressure, temperature and contents being managed. Additionally, make sure to routinely have the valve maintained and inspected to ensure that it works properly and to prevent any possible problems.
Sizing a pneumatic butterfly valve
To sum up, sizing a pneumatic butterfly valve for industrial pipelines is an essential procedure that should never be taken lightly. In meeting the valve sizing requirement, pipeline industries should understand the importance of valve sizing, learn about how to select correct size influenced by intrinsic factors, follow sizing requirements and valves selecting recommendations in order to prevent any ill effect caused by incorrect valve sizing which will create an efficient flow control system with optimal performance. By taking these precautions to size a pneumatically operated butterfly valve properly, you can improve function for flow control and increase productivity of your industrial systems.
