Now i feel silly and stupid! Let me try and be specific.
In the attached image, the blue ones are pneumatic cylinders (air).
The cylinders will be controller using a 3/4 Port Solenoid Valve.
There are reed switches(S) on the pneumatic cylinder which i will use as position feedback to my electronic circuit.
First, Cylinder 1 in position S1 will be actuated to S2.
When S2 goes high cylinder 2 actuates towards S5.
When S4 goes high cylinder 3 actuates towards S6.
When S5 goes high cylinder 4 actuates towards S8.
Initial position S1,S3,S7,S9.
All cylinder are dual acting.
Solenoid valves control which way the air goes.
Your option list seems to be a closed set, because you don't know what's required and what's available.
You got that one right. I am new and i don't know how things work in practice and what are some of the standards of the industry.
