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.
