Who works in the hydraulic/pneumatic field here?

I *cough* borrowed *cough* some 4/5 port solenoid valves from work, SMC VZ3140 with the intentions of elec/vacuum my my maxidrives, these baby's should be perfect, problem is sourcing 12V coils, they came with 240V, when I priced the coils........126 beer tickets each , the whole assembly is only 174, I'm just wondering if their is someone who gets a decent price from a wholesaler here, Thanks

i dont know if this company is down in vic but they are called southcoat there are the cheapest i know for hyd shit

ill have a look on the junk shelves at work tomorrow i should have some 12v coils around somewhere.

i have 2 spares from my shock set up what is the internal dimensions of the coils?

I used to work in the oil-gas industry where a lot of pneumatics are used (not that long ago that all control-gear was pneumatic), and had a swag of such gear on my vehicle. The big Omron programmable relays on bases would spin people out.
I found that 24VAC coils will pull-in and hold on 12VDC, so maybe see if they have any of these coils.

That's a bit tricky You little devil... you!!

I was just going to say i only really see 24v ones, hadn't tried the above, keep me posted on how you go, might be able to help....

Are you using these valves for vacuum? Reason i ask is some pneumatic valves use air/pilot pressure to shift once the coil is activated. No SMC info at home so cant check this particular valve but may pay to check it out before you fit it all up.
Have run 24volt hydraulic solenoids on 12v before but sometimes they wont shift if voltage is a bit low (will hold once shifted tho), so if you try this, you may have to use a relay to make sure you get full battery voltage (14v) to coil. I would think coil life would prob be shortened tho.

We use a lot of GOYEN & METALWORK pneumatics and the coils are not inter-changable.


Should check the valve to see if its going to do what you need.ie is it a N/O(normally open) or N/C (normally closed).

If they don't work with vacuum - just swap the lines over and run the MDs with 15psi compressed air. It's what I do.

But I've alrady got a vacuum source , Its got a boost source to but only when you give it stick

Sorry for the lack of replies, chasing up some option with a rep. at the moment
