Miniature, accurate, long-life proportional valve

Emerson has introduced the Preciflow 12.7mm miniature proportional valve fromASCO Numatics. The valve is claimed to feature one of the smallest footprints on the market combined with accurate flow control, suiting it to a range of applications, particularly those in the analytical and medical industries.

The Preciflow 12.7mm integrates key features, including two internal flat springs that allow the core to float freely, minimising friction during operation. These are said to result in reduced wear and tear, increasing the valve’s life-span and ensuring its accuracy over time.

With typical hysteresis rated at 5%, Preciflow 12.7mm is said to provide accurate and repeatable control. Its suitability for oxygen service use makes it an ideal solution for gas chromatography and mass spectrometry applications, and its low power consumption offers added value to end users.
