Emerson launches Sentronic proportional pressure control valves

The new valves, with a control deviation of less than 0.5%, are engineered for highly accurate electronic proportional pressure control, offering the flexibility needed for advanced pneumatic control engineering applications.

The Series 625 Sentronic valves include data acquisition software (DaS), enabling quick startup, monitoring, and control directly from a PC.

Available in four sizes ranging from 1 millimetre to 20 mm, these valves support flow rates from 55 to 4,700 litres per minute.

Specifications

They can handle pressures from vacuum levels up to 50 bar, potentially reducing the number of valves needed in a machine design. Housing materials include brass, aluminium, and stainless steel, with sealing options in nitrile (NBR) or fluoroelastomer (FKM). Connector options are M12 5-pin, M12 8-pin, and M16 7-pin.

With the trend toward shorter development and manufacturing phases, fast startup procedures and reliable, controllable manufacturing processes are increasingly critical. DaS software allows operators to diagnose, control, repair, and configure valves individually. It also supports cascade controls for applications requiring high precision and complex control loops. Enhanced diagnostic and monitoring functions include input pressure, commanded pressure, internal temperature, and ethernet communication.

“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.”
