Measurement of Pneumatic Valve Flow Parameters on the Test Bench with Interchangeable Venturi Tubes and Their Practical Use

Abstract: A test bench with interchangeable venturi tubes was built to automatically measure the flow parameters of pneumatic valves of a wide range of sizes. This measuring stand contained components recommended by the ISO 6358 standard, an individually configured flow meter circuit, and HMI measurement and control panels. The flow meter circuit, individually configured with interchangeable venturi tubes, bypass loops, and Setaram thermal microflow meter, was calibrated using Molbloc/Molbox equipment. The tuning curve … Show more

“…The nominal diameter d n (in technical practice, the designation DN is used according to the French name diamètre nominal) is the standard parameter. Sonic conductance C and critical pressure ratio b can be calculated using measurements of the flow parameter from the test bench [60], as follows:…”
