Emerson has introduced the new AVENTICS Series 625 Sentronic Proportional Pressure Control Valves. With a control deviation of less than 0.5%, the new valves are designed to deliver highly accurate, electronic proportional pressure control and provide the flexibility needed to support sophisticated pneumatic control engineering applications. Data acquisition software (DaS) included with Series 625 Sentronic valves also makes it possible to quickly start, monitor, and control valves directly on a PC.
“In high-precision equipment, such as that used for flame cutting and laser eye surgery, accuracy, and control are critical,” said Nicolas Jacquet, director of product management for Emerson’s discrete automation business. “Series 625 Sentronic valves are engineered to precisely control pressure, flow rate, power, speed, distance, and angular positions. As part of the extensive AVENTICS portfolio of cylinders, valves, air preparation, and pressure regulators, the Series 625 Sentronic is a core technology for factory automation.”
Four-valve sizes from 1 mm up to 20 mm support a comprehensive range of flow rates, from 55 to 4,700 l/min. Pressure capabilities range from vacuum levels up to 50 bar, which can reduce the overall number of valves required for a machine design. Housing material is available in brass, aluminum, or stainless steel, and sealing material in nitrile (NBR) or fluoroelastomer (FKM) options. There are also three sets of connectors, M12 5-pin, M12 8-pin, and M16 7-pin.
As development and manufacturing phases get shorter, fast startup procedures and reliable, controllable manufacturing processes are more important than ever, operators can diagnose, control, repair, or individually configure valves using the DaS software. They can also perform cascade controls when applications require exceptional precision and other complex control loops. The expanded range of diagnostic and monitoring functions includes input pressure, commanded pressure, internal temperature, and Ethernet communication.
