The new Cordis HP500 from Cincinnati-based Clippard uses the company’s proven EV line of electronic valves to allow for steady, repeatable downstream pressure under static conditions. The result is precise, linear pressure control within a closed-loop system with high accuracy and repeatability. The Cordis HP500 uses a microcontroller, integrated pressure sensor, and two Clippard EV […]
What are alternatives to Cv for rating flow?
The flow capacity of valves, connectors and other components in pneumatic systems is often expressed in Cv. (See, “What is the flow coefficient Cv?“) However, other methods and standards are also available to express flow capacity. Here are some important alternatives. Sonic conductance In place of Cv, some manufacturers choose to publish the sonic conductance, […]
What is the flow coefficient Cv?
In the pneumatic industry, Cv is one standard for expressing the flow capacity of devices used in pneumatic systems. However, there are multiple other standards that also express flow capacity, including effective orifice size and normal liters per minute, as well as measurements of actual flow rates at specific pressure differentials. These methods are not […]
