Festo SEU-1/8 4616 G1/8 Quick Exhaust Valve with Silencer

Festo SEU-1/8 is a quick exhaust valve with integrated silencer. Installed directly on the cylinder port, it enables rapid exhaust of compressed air to atmosphere, increasing piston return speed in single‑ or double‑acting pneumatic cylinders. The built‑in silencer reduces exhaust noise.

Applications:

• Increasing piston return speed in single‑acting cylinders

• Rapid exhaust in double‑acting cylinder circuits (installed between valve and cylinder)

• Packaging machinery and pick‑and‑place systems

• Factory automation requiring shorter cycle times

System Integration:

• Install directly on the cylinder port (between directional control valve and cylinder) for maximum exhaust speed.

• For double‑acting cylinders, use two valves or install on the return stroke side only.

• For detailed installation diagrams and pneumatic circuit schematics, refer to the product hardware manual.
