Hydraulic Clamp Sequence Control

Hydraulic clamp sequence control circuit

This example shows a simple electrical sequence for a hydraulic clamp. Pressing Cycle Start energizes the clamp relay and its valve solenoid. When the clamp reaches the configured position, a limit switch changes state and energizes a second relay that operates the release-valve solenoid. The example is deliberately small so the relationship between command, feedback, and output stays easy to read. It can help a maintenance technician explain a basic fixture sequence or help a designer sketch the control intent before adding a controller. Real clamp systems often require guard switches, two-hand control, pressure confirmation, timeouts, and a safe release strategy, all of which should be engineered for the actual equipment.

O que há neste desenho

Entenda as decisões por trás dele.

01Cycle start

A pushbutton begins the clamp command.

02Position feedback

A limit switch signals that the clamp has reached its position.

03Release output

A second relay and solenoid command the release valve.

Use as a starting control sequence for a fixture or press clamp, then add timing, guarding, and safety logic for the machine.

Perguntas frequentes

Dúvidas comuns

What is a clamp limit switch for?

It provides position feedback when the clamp reaches a defined point in its travel.

Why use a separate release solenoid?

It commands the directional valve to move fluid in the direction that opens the clamp.

Is this sufficient safety control for a press?

No. Press and clamping safety requires a machine-specific risk assessment and appropriate guarded safety controls.
