Can a pneumatic valve be controlled via a pneumatic circuit?
Thread Content
Pneumatic valves are controlled for opening/closing using compressed air on-site
Obviously, it’s possible; it depends on the specific requirements
Compressed air needs to be treated before it can be used; instrument air is preferred
We can just draw inspiration from the directional control valve in hydraulic stations.
This is acceptable; compressed air can, to some extent, be considered factory air, and it’s not as clean as instrument air
