3/2 pneumatic valve help

[Danjr1]

Afternoon all,
I'm designing a simple 10bar system and need a little help working out which ports are what on the following solenoid valve

http://www.ebay.co.uk/itm/3805306028...888%26_rdc%3D1

I'd be using bungee cord to return the piston so I'm hoping that the ports inline with each other could be used for the gas input and output, then the port on the side as exhaust. I'd obviously be using a 12v solenoid in place of this version.

Cheers

Dan

"AC 220V".... meaning it needs 220volts AC to fire it... look for one with a 12 or 24v coil.

I've been searching and I don't think it would work. According to the two websites below, the port on the side is the inlet and the two ports inline with each other are the outputs. Could someone please just confirm that I've read that right?

According to the diagram in the first link it should be fine as a 3/2 valve. Your actuator port is connected to A allowing it to normally vent. When the valve is operated your supply (P) is connected to the actuator (making it go up).

you might want to go a step further and get yourself a 5/2 valve with qev and buffer tank for a more powerful system, its still low press but slightly more complex. Imho it's worth the extra effort.

Cheers all. Kane, just so I'm clear, I'd connect port A which seems to be the port at right angles to the others to the cylinder then whichever one port P is to the co2 system? Just a pain that I'll have to add another right angle to the system!

Liftoff, I looked at 5/2 LP systems before but it was the weight and complexity that put me off.

Does anybody know what the flow rate of a 10 bar paintball regulator and a 3/8" 3/2 valve are separately in litres/ minute? just rough approximations would be fine, trying to use the hassocks hog pneumatic calculator to help design the system. I won a 80mm bore 40mm stroke cylinder on eBay so need to get a move on with the rest of the system!

Dan you mind me asking what what's the pneumatic system for, is it a flipper, lifter etc? Reason I ask is that with this set up I see it will be a bit slow reacting. I got a LP paintball reg and a 1/2" 5/2 valve, but that's only the size of the fitting it will take. The actual port hole will be much smaller. Same with the regulator, flow rate is very small, the inlet is barely 2mm in diameter! Check the port sizes of the ram as well, although it might be listed as 3/8" inlet/outlet, the actual hole will be much smaller. If the set up is for a lifter, then it's ok, but I can't see it will make a decent flipper without modifying your setup

[Danjr1]

will need to have another proper think about the design. cheers for the advice!
