The AVENTICSTM Series 625 Sentronic Proportional Pressure Control Valves has been announced by Emerson. 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) software included with Series 625 Sentronic valves also make it possible to quickly startup, monitor and control valves directly on a PC.
Four valve sizes from 1 millimeter up to 20 mm support a comprehensive range of flow rates, from 55 liters per minute 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 continue to get shorter, fast startup procedures and reliable, controllable manufacturing processes are more important than ever. Using the DaS software, operators can diagnose, control, repair or individually configure valves. They can also perform cascade controls when applications require exceptional precision and other complex control loops. The expanded range of diagnostic and monitoring functions include input pressure, commanded pressure, internal temperature and ethernet communication.
