Overview
The Festo MOFH-3-M5 is a compact electrically-actuated pneumatic solenoid valve designed for precise directional control in compressed air systems. This 3/2-way, normally open valve features a single solenoid coil, mechanical spring reset (monostable operation), and integrated manual override for manual actuation when needed. With soft sealing poppet design, the MOFH-3-M5 minimizes internal leakage and ensures reliable cycle-to-cycle performance in automation and machine control applications.

Typical Applications
The MOFH-3-M5 solenoid valve is used across diverse automation and pneumatic control systems:
- Pneumatic Actuator Control: Direct or pilot actuation of cylinders, grippers, and rotary motors in assembly lines and material handling.
- Machinery Automation: Directional control in packaging equipment, printing systems, textile machinery, and food processing.
- Manual Override Diagnostics: The integral override allows field technicians to troubleshoot and manually position actuators without electrical power.
- Pilot-Operated Systems: Efficient control of moderate-flow circuits where solenoid coil energy efficiency is important.
- Process Automation: Reliable switching for sequential pneumatic processes in manufacturing plants and OEM equipment.
