Cylinders in Series

Can a single directional control valve operate 2 cylinders if each cylinder uses a breather valve instead of a return line so that one cylinder would push the other closed?

Mono Block Valve

Sorry but i forgot how to post a new question and just jumped in this .
iam having a problem with gear pump witch is connected via a monoblock to a pressure guage.
problem is that when i switch the dcv 'on' the guage showes 190 bar ,but for just for one second
then it start to go doun to 100 bar and stay at 100 bar.

as i switch off and then on again
it goes to 150 and then goes down again.
is it relief walve which is releasing pressure and not settlig down again till pressure goes down to 100 bar , if it is pressure should rise again .can a pilot oprated relief solve this .
forgive me for a so basic and not mind frying question.
