Little Hydraulic Arm

I'm still learning electronics and the Netduino but just wanted to float a question out there to see if I'm going in the right direction. I'm trying to control a small hydraulic arm (just a cylinder and a rod that goes out and back) and I was thinking I'd need a small air pump and a three way solenoid valve (one way to pump/push the arm out and one to release the air letting a weak spring in the cylinder push the arm back.
Anyone seen a netduino/arduino project like that or any components that might suit. Any help at all most gratefully received.
Many Thanks in advance.
I think your looking for a solenoid actuated spool valve. In my experience, I've only used them with PLC's to actuate powerful hydraulic servos so I'm not exactly sure of the availability for something small scale.
If you shooting for small scale, I would actually use two small solenoid valves with a pressure relief valve feeding back into my supply reservoir.
