Festo MHE2-MS1H-3/2G-QS-4 196135 electrician tool

Product Identity

The Festo MHE2-MS1H-3/2G-QS-4 is a 3/2-way air solenoid valve designed for pneumatic control systems. It suits automation engineers and maintenance technicians who need reliable directional control for compressed air circuits. The valve operates as a single-stable unit with a mechanical spring return for defined fail-safe positioning. It is not intended for hydraulic fluid or high-pressure gas applications beyond its rated pneumatic range.

Capacity and Headroom

The valve provides standard flow capacity for typical actuator control in machine building and process automation. Its quick-connect ports accept 4 mm tubing for fast installation without threaded fittings. The monostable design ensures the valve returns to its default position when de-energised, simplifying safety logic. Systems requiring bistable latching or higher flow coefficients will need a different valve series.

Thermals, Noise and Power

The solenoid coil is rated for continuous duty at standard industrial voltage levels with low heat rise during extended operation. Switching action is quiet, producing only a light mechanical click suitable for noise-sensitive environments. Power consumption remains minimal, allowing multiple valves to share a common power supply without excessive load. The red housing aids visual identification in dense valve manifolds.
