I know what a burst disc is. I think I have spotted where its mounted now in the pictures on the first page. The base of the ram is propped up against it which is what was confusing me.Originally Posted by Rahulvyas
Chris, where did you get your Burst Disc units from? Ebay and Google are only showing units that blow at a minimum of 1800psi, I need around 200-260psi for a low pressure system.
You don't need a burst disk for the low pressure side of the system, you only need a pressure relief valve.
I believe what Chris is suggesting is you can remove the burst disk from the valve (presumably with the centres drilled out to increase flow) and replace it with an ordinary ball valve to act as your dump valve.
Yeah, I reached the same conclusion about 20 minutes ago :-P
Yep thats right, spot on Max. I used the pin valve which came with the tank, drilled the centre away and took the burst disk off. That way there will be no restrictions from buffervto qev.
@Rahul, I don't do any FP systems, better someone with hands on experience to give you an answer
Ok, another thing what is the bore and stroke of the cylinder that you are using in your bot?
63mm bore 75mm stroke
Using Chris' parts list and advice from many of you guys, I've finally got a pneumatic system that worksNow to design a robot around it...

single acting, cool.
What are the specs of your pneumatic cylinder?
It look like a 40 Bore 75 Stroke. Nothing amazing but it can put a robot out of our arena if attached to the right robot.
It's this one from eBay, 50mm bore 45 mm stroke. Modified like Chris suggests by drilling port holes bigger and had to drill and tap an exhaust port at the bottom to vent it after it's fired.
