Festo K-3-M5, Pushbutton Valve

The Festo K-3-M5 is a compact pushbutton valve used to control airflow in pneumatic systems manually. It is commonly installed where operators need quick on-off air control without electrical signals or automation. Pressing the button allows compressed air to pass, and releasing it stops the flow immediately. This valve is often used in basic control circuits, test setups, and small machines where simplicity and reliability matter more than complexity.

Core Capabilities of the Festo 3660 Pushbutton Valve

The valve operates mechanically through a pushbutton. When pressed, the internal mechanism shifts and opens the air path. When released, it returns to its normal position.

• Manual pushbutton operation.
• Instant response without delay.
• No power supply required.
• Works reliably even in environments where electrical components are not suitable.

Manual Control Valve for Simple Pneumatic Tasks

The K-3-M5 is small and lightweight, making it easy to mount in control panels or directly on pneumatic lines. The M5 port size is suited to low-air-flow applications and compact pneumatic circuits. It is typically used with clean compressed air and integrates easily with standard pneumatic fittings, tubing, and accessories.

Broad Range Application

It is especially useful when operators need direct control without relying on sensors, solenoids, or controllers.

• Manual start or stop of the air flow
• Test benches and training rigs
• Simple pneumatic control panels
• Safety or override air control points
