Pneumatic Valves

[Brad93]

How would one go about describing this valve?

I need to source a replacement, possibly two
replacements as i doubt a modern valve will bolt together with the old one?

They run on cams which does the timing of bottle feed on a filling machine.

Most online seem to involve a lever arm rather than direct acting like those

Any replacement would require the same movement characteristics as the original (simple example fully open to fully closed over 1/2" stroke of plunger) or you will need to fiddle with the cams.

Please look at their 1800 series as they are available with a cam roller actuator.

Those are 5/2 (5 port, 2 position) and a search for "5/2 roller pneumatic valve" should generate some hits. Most are lever-roller, as said above. I think a direct-roller will probably be quite pricy by comparison.

As said above

5-2 valve.
Hayleys or similar will be able to find something to do the job.
Looks like spring return with roller follower.
