Festo MN1H-2-1/2-MS 2/2 NC Solenoid Valve G1/2 10bar 3100L/min 161728

Overview
The Festo MN1H-2-1/2-MS (part number 161728) is a robust, pilot-operated 2/2-way diaphragm solenoid valve designed for reliable on/off control of compressed air and other gaseous media in industrial automation systems. It is a normally closed (NC), monostable valve, meaning the valve remains closed in its de-energized state, providing a secure shut-off for safety-critical applications.

The valve features a durable brass housing with high-alloy stainless steel screws, making it suitable for harsh industrial environments. It operates with various voltage options (24V DC, 110V AC, 230V AC) and is equipped with a standard Type A plug connection according to DIN EN 175301-803, ensuring easy integration into existing systems.

With a G1/2 connection thread and a high flow rate of up to 30,500 l/min, this valve can handle large-scale pneumatic systems and demanding applications. It includes a manual override for commissioning and maintenance without electrical power, offering exceptional flexibility.
