Hello
I'm studying to become a marine engineer, and at the moment I'm working on a project:
Build an exo skeleton.

Something very similair to this:


I've figured 2 ways out to install the pneumatic, and I just wanna know if you wanna do something different.

1. ------------------------------------------------------------------------------------------------------------------------------------------------------- 2.


The idea is, that the valve will return to the middle position automaticly, when you let go of the handle, and hold the cylinders will hold their position.

Option 1:
4/3 valve
The air will just flow out of the cylinder, and you have to pull down yourself, or the load will pull down for you

Option 2:
Ordinary 5/3 valve

I want the restrictors, so I can adjust how fast the cylinders will rise and fall.

Did I do it right?
Thanks in advance

not sure if this helps, but maybe put in a proximity switch , like a limit switch
or think about a double acting actuator versus a spring return actuator on the valves?

not sure what application this is. im a controls engineer, but this may be a totally different subject here

So you want a basic supply air to frl to one of the two dcv's to check valve with variable flow control then to the load devices which in this case will be two single-acting linear actuators? Blocked in one direction and free flow in the other???


#1 problem being you'd have to tighten the set screw all the way down and would have to manually release the air via loosen set screw on free flow valve with check valve intrical.

#2 looks good!


Just try it out with a regulator or filter regulator lubricator in line with the supply air so you do not get knocked out when the actuator extends... (I'm a bit rusty)

Also, My mobile bandwidth has been throttled so I can not watch videos. I'm only going by experience.

Edited too many times..

Also The symbology is a bit different than how I learned so the dcv is not exact but the concept of where you are going is in the right direction considering I am understanding how you want to plumb it.
