Overview
The Festo MN1H-2-1/2-MS 161728 is a compact, electrically actuated solenoid valve designed for direct control of filtered compressed air in process automation and industrial pneumatic systems. This 2/2-way valve features a brass body, G1/2 connection, and is designed for single solenoid coil actuation. The monostable design with manual override provides both automatic and manual control capability in confined mounting spaces.
Key Features
- Diaphragm valve design — Soft sealing principle with minimal leakage
- 2/2-way, closed monostable function — Normally closed until energized; spring-returns when de-energized
- Brass construction — Corrosion-resistant housing with high-alloy steel trim
- Manual override — Non-detenting manual push for emergency or manual operation
- DIN EN 175301-803 electrical plug connector — Type A plug pattern, industry-standard interface
- Optional mounting position — Flexible installation orientation; in-line piping installation
