Recommendations – Proportional Directional Control Valve for Pneumatic Cylinder


I am building a pneumatic robot leg and already have on hand two components:

1) 100mm double acting mini cylinder

  • Thrust = 100.5N, tension = 86.4N under pressure 0.5MPa, 16mm bore

2) 12V 120psi air compressor

I am looking for a suitable proportional directional control valve that would allow me to control position of the piston rod. That is move the rod to desired position and hold it there. So I did some research and think that 5/3 valves look like they would work?

Appreciate some advice on what type of valves can be used for such a purpose and if additional accessories are needed to complete the system.
