2 controls 1 output hydraulic control

[fruc]

Hi there

I'm trying to do something similar as I sketched in the picture below.

probably something like this already exists so if anyone can point me in the right direction.

So I want to control one cylinder with two controls
si if either one or the other or both controls are on the cylinder has to engage. When it is released the cylinder should retract because of the spring.

Thank you very much in advance.

Use one electric solenoid valve and two push buttons.
It will save you three cylinders and a solenoid valve.
