Hydraulic Cylinder Control Circuit

Hydraulic cylinder control circuit

This example shows the low-voltage electrical control side of a double-acting hydraulic cylinder. A fused 24 V supply feeds two momentary commands. The extend pushbutton energizes one relay coil and its directional-valve solenoid; the retract pushbutton energizes the other pair. The labels make it clear which command shifts which side of the 4/3 valve. This is useful when documenting a basic press, clamp, lift, or fixture before adding limit switches, interlocks, or automatic sequencing. The drawing does not replace the hydraulic schematic: the pump, reservoir, relief valve, hoses, and cylinder ports still need to be specified in the machine documentation.

“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.”

次はこちらAdd a normally closed stop pushbutton.Change the control supply to 12 V DC.

図の背後にある意思決定を読み解く。

01Separate commands

Extend and retract have their own pushbuttons.

02Fused supply

A 2 A fuse protects the low-voltage control circuit.

03Two solenoids

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.

よくある質問

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.
