That is a 'Hit hard, hold' type of cycle, where there is a strong initial knock to crank the 'noid over and then a small holding setup. We could use a far smaller 'noid for this operation.
With the 'switch' it is basically a larger soleniod valve internal, though with a custom route to cut off air supply and connect internal air to cycle the gun. This is because we route the supply air through the switch also to recharge the gun. So something off the shelf (even in a larger format) wouldn't work either.
We basically use the Mac33 as a pilot, like the SMC SY is mated to a SYJ solenoid to cycle it. Just - bigger. Hence the low 'noid on time. The Mac33 is overkill for the pilot, the switch is complete overkill.
We will see what testing we can do to cover the cycle time, we want to know that also. I guess I can justify a higher speed camera and maybe a transducer or two...
