Reduced heat transfer to the media with media-separated valves
In laboratory automation, many liquids are used that react sensitively to heat. One possible factor for the transfer of heat to the fluid are media-separated solenoid valves, which are usually actuated electromagnetically. The valve series VYKx from Festo reduces the transfer of heat to the media to a minimum.
In medical diagnostics, the transfer of heat to temperature-sensitive fluids can significantly impair the reliability of the results, whether for blood, enzymes, reagents, solutions or buffers. That is why, when developing the media-separated valves of valve family VYK, Festo exhausted all possibilities to minimise the influence of temperature, from a heat-optimised design and holding current reduction to the option of placing the control electronics in a decentralised location. Valve VYKA in particular impresses with its extremely low transfer of heat. Watch the video to find out more about how you can use this solution to optimise the reliability of temperature-sensitive applications.
The success factors for minimal heat transfer
The application engineers from Festo have analysed which factors in the design of a valve unit influence the transfer of heat to the media and produced specific recommendations based on this. They also carried out tests on the transfer of heat to fluids with media-separated Festo valves and comparable products from other manufacturers. The results of the comparative tests and the recommendations can be found in our Application Note.
