the ball valve wont be fully open before the ram has reached end stroke

Are you sure?

OK ...What is the opening time of a 1 bore 3 stroke ram when supplied with 150 psi by a std 1/4 port 5/2 valve with a Cv of around 1.2?



The ram setup I suggested had a LOADED opening time of 0.12 sec... So...

BTW ..What is the opening time for a Burkert ?
