“Draw a 24 V control circuit for a double-acting hydraulic cylinder with a fused supply, extend and retract pushbuttons, relay coils, and two solenoids for a 4/3 directional valve.”
Read the decisions behind it.
Extend and retract have their own pushbuttons.
A 2 A fuse protects the low-voltage control circuit.
Each coil shifts one side of the directional valve.
Use this as a simple electrical control reference for a cylinder valve; document hydraulic power and hose connections separately.

Common questions
What does a 4/3 valve do?
It has four ports and three positions, allowing a double-acting cylinder to extend, retract, or hold according to its spool center.
Why are there two solenoids?
One solenoid commands one spool direction and the other commands the opposite direction.
Is this the hydraulic power circuit?
No. It is the electrical control circuit for the valve solenoids; draw the fluid path separately.
