Mini servo valve - geared

thingiverse

I required a compact motorized valve to create an authentic environment simulation for liquid flow. A direct valve drive design has a torque issue because the servo I wanted to use is too feeble to function properly in that mechanism. To achieve balance between speed and torque, I selected a gearbox with a 1:1.5 ratio (16:24 teeth). The valve is compatible with Festo's HE-2-QS-8 model, which features 8mm terminals. The greatest advantage is that it actually works even with extremely low-quality, inexpensive servos.
