No, the ram is max 16 bar. Full Pressure is 60 bar
Yeah, I don't understand that leverage ratio.Originally Posted by maddox10
Isn't a upward flipper a class 3/C lever, at a mechanical disadvantage but increased tip speed?

For full pressure (1000 psi/70 bar max, but CO2 at 20°C is only 55 bar, and that will drop if it cools down during use) use you have 2 options. An hydraulic ram is strong enough to take the forces involved and is allowed. Or else a custom FP ram, with the right credentials. These custom FP rams don't grow on trees.Originally Posted by psychostorm
Correct. Diminish force to gain speed.Isn't a upward flipper a class 3/C lever, at a mechanical disadvantage but increased tip speed?
sorry, meant to put in link to this ram:

this one is hydraulic so is rated high enough bu same questions again,
also, how do you weld hardox and is it the same weight per volume as normal ild steel?Originally Posted by Max
At that price you might aswell get a custom pneumatic cylinder made.
You weld hardox using the same methods for mild steel. Effectively yes it has the same density but type hardox density into google and you will find the exact value (it's late and I'm too tired to bother)
I am hoping to be able to get a similar ram at a reduced price from my dads friend. But are those ports big enough if not what size do others use?
So for hardox can you buy special 'sticks' for use with an ark welder? Also where do people get it from?

Seriously, google is your best friend
You can just use regular mild steel welding electrodes (sticks) to weld it

The cylinder you linked to has a Port Size #4 SAE = 0.172 min dia

All the above is just a rough guide .... real world has many other variables.
EG ..Can you open the supply valve fully in less time than the math value for the ram extension time?
that table is awesome! but what is Cv flow?
Cv is a flow value / rating ... a measure of how well the fluid / gas flows thru the pipes / orifices.
