Re: Oscillating a pnuematics valve?

the problem with using two valves to create a multiposition system is that the arm is balanced by the pressure in the cylinders. If you pulled or pushed on the arm at any given position, the arm would move (for example, if you dropped a tetra, the arm would rise up on its own).

using a locking mechanism, or clutch, would make the arm stiff in all positions.
