By Melonie Dodaro , Valve World
Emerson has introduced the AVENTICS Series 625 Sentronic proportional pressure control valves , designed to deliver highly accurate electronic proportional pressure control for sophisticated pneumatic control engineering applications . With a control deviation of less than 0.5 %, these valves offer the flexibility and precision needed in high-precision equipment , such as flame cutting and laser eye surgery machines . The Series 625 Sentronic valves are part of Emerson ’ s extensive AVENTICS portfolio , which includes cylinders , valves , air preparation and pressure regulators . The valves are available in four sizes , ranging from 1 millimetre to 20 mm , supporting flow rates from 55 litres per minute to 4,700 l / min . Pressure capabilities range from vacuum levels up to 50 bar , potentially reducing the overall number of valves required in a machine design . Housing materials for the Series 625 Sentronic valves include brass , aluminium and stainless steel , while sealing materials are available in nitrile ( NBR ) or fluoroelastomer ( FKM ) options . The valves also feature three sets of connector options : M12 5-pin , M12 8-pin and M16 7-pin .
Advanced diagnostics and monitoring capabilities
To support fast startup procedures and reliable , controllable manufacturing processes , Emerson has included Data acquisition software ( DaS ) with the Series 625 Sentronic valves . This software enables operators to diagnose , control , repair or individually configure valves directly from a PC . The software also supports cascade controls for applications requiring exceptional precision and other complex control loops . The DaS software provides an expanded range of diagnostic and monitoring functions , including input pressure , commanded pressure , internal temperature and ethernet communication . These features ensure efficient operations and help manufacturers adapt to shorter development and manufacturing phases . “ Series 625 Sentronic valves are engineered to precisely control pressure , flow rate , power , speed , distance and angular positions ,” said Nicolas Jacquet , director of product management for Emerson ’ s discrete automation business . “ As part of the extensive AVENTICS portfolio , the Series 625 Sentronic is a core technology for factory automation .” The AVENTICS Series 625 Sentronic proportional pressure control valves demonstrate Emerson ’ s commitment to providing innovative solutions for the world ’ s essential industries . By offering precise control and flexible configuration options , these valves help manufacturers optimise their operations and achieve their sustainability goals . www . valve-world . net Valve World September 2024
