States for SMC 3 position valve

Two position dual solenoid valves stay in the last state energised. IE extended or retracted which is what you are describing?

I have absolutely verified that the SMC valves that we have are 3 position. Do you know how to lock piston position in the programming (in Java) using these types of valves? The model number is: SY5320-6D-N7T.

P.S. The 'DoubleSolenoid' and 'Solenoid' I was referring to were Java objects.

Without knowing the what the actual valve is, I cannot give any advice on programming it.

On the physical side. If you cannot fully vent the pneumatics from the high pressure vent, your pneumatic system isn't FRC legal. Closed center three posittion valves tend to prevent that
