Same tool, four requests. Every drawing below is a real render.

What you type

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.

Then tryAdd a normally closed stop pushbutton.Change the control supply to 12 V DC.

The drawing

What a hydraulic circuit diagram is.

A hydraulic circuit diagram shows how a hydraulic machine is controlled: its power source, valves, actuators and the signals that command them. The fluid circuit and the electrical control circuit are often documented together as related drawings.

Use the electrical control drawing to trace switches, relays and solenoid valves. Use the hydraulic schematic to trace fluid from the reservoir and pump through the valves to cylinders or motors.

FAQ

Common questions

What is a hydraulic circuit diagram?

It documents how pressurized fluid is supplied and directed through valves to cylinders or motors, together with the controls that command the system.

What components should I include?

Describe the pump or power unit, reservoir, pressure protection, directional valves, actuators, supply voltage and the switches or sensors that command the valves.

What is the difference between hydraulic and pneumatic circuits?

Hydraulic systems use pressurized fluid and return it to a reservoir. Pneumatic systems use compressed air and normally exhaust it to atmosphere.

Can I add pressure and flow specifications?

Yes. Include pressure, flow, cylinder dimensions or valve configuration in the description when those labels are needed.
