The RRV 187 Rapid Reaction Valve is especially suitable for the pressure reduction and dosing of small amounts of gas or fuids. Due to the small size of the ball it is possible to control the valve also with very high frequencies (up to 1000Hz). This leads to a nearly continuous fow control. The ‘singing valve’ is actuated with extremly short circuit gime in the millisecond range. At these circuit times, very high frequencies (up to 1000Hz) are created which can be noticed as sound. The valve is suited for a pressure range fom 0.5 up to 150bar,a fow-rate 0.05m3/h and a maximum viscosity of 600mm2/s. Supply voltage is 2-10VDC and 24VDC with electronics. The device weighs just 95g and is protected according to IP56.

PCN Europe’s March issue features an Industry Special covering issues concerning the Environment, we look at the role heat management plays in the world’s largest CO2 test facility, in another one we discover a zero liquid discharge treatment process for waste water. Our Product Focus on Measurement Technology includes among others an application story showing how predication and performance monitoring on a oil & gas platform enables onshore personnel to monitor essential equipment. In our technical article we look at ways to eliminate mechanical issues in differential pressure systems. At this time of the year we are looking forward to the trade show season, especially at Hannover Messe, the leading industrial trade show. This edition also presents you with many other application stories and product news from all areas of the processing industries, enhanced with datasheets and videos.
