PROCESS EQUIPMENT UPDATE
HIGH PRECISION
lobal technology giant Emerson has launched the Aventics Series 625 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 Data acquisition software (DaS) included with Series 625 Sentronic valves also make it possible to quickly startup, 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,” says director of product management for Emerson’s discrete automation business Nicolas Jacquet. “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.”
VALVE SPECIFICATIONS Four valve sizes from 1mm up to 20mm support a comprehensive range of flow rates, from 55 litres 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, aluminium or stainless steel and sealing material is available in nitrile (NBR) or fluoroelastomer (FKM). There are also three sets of connectors, M12 5-pin, M12 8-pin and M16 7-pin.

A new control valve series comes with PC monitoring and control capabilities
Series 625 Sentronic valves are engineered to precisely control pressure As development and manufacturing
phases get shorter, fast startup procedures and reliable, controllable manufacturing processes are more important. 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.
