Festo MFH-3-1/8 7802 Tiger Classic 3/2 Pneumatic Solenoid Valve

Festo MFH-3-1/8 is a solenoid‑operated pneumatic directional control valve from the Tiger Classic series. It features a 3/2‑way (3‑port, 2‑position) monostable function, normally closed (NC), with a distinctive Tiger Classic body shape. A spring‑return mechanism ensures failsafe operation. The valve can be mounted on PAL manifold strips or PRS manifold blocks for efficient system integration. For applications requiring manual intervention, a manual override is provided. Nominal flow rate is rated at 500 L/min at standard conditions.
