Airtec solenoid valves
Airtec solenoid valves are modular pneumatic valves for controlling single-acting and double-acting cylinders and for bistable switching tasks. The range extends from compact 3/2-way types (G 1/8" to G 1/2") through 5/2-way valves with spring or air-spring return to 5/3-way valves with three defined centre positions. External-pilot versions (ME series) and magnetic impulse valves (KM series) complete the programme for Ex zones and energy-saving applications.
The HN versions incorporate a manual override that allows the valve to be switched manually during commissioning or in the event of a PLC failure. Valve manifold stations built from RF intermediate plates, end plates and blanking plates allow the assembly of compact valve islands with shared compressed air and exhaust connections.

How to choose Airtec solenoid valves
What matters when choosing: properties, comparison and typical applications.
Valve configurations and features
Valve type comparison
| Type | Way | Function | Typical use |
|---|---|---|---|
| M / MO (Standard) | 3/2, 5/2 | Monostable, spring NC/NO | Single/double-acting cylinders |
| KM / M (Impulse) | 3/2, 5/2 | Bistable, impulse | Energy-saving control, long hold phase |
| KM (5/3) | 5/3 | Bistable, 3 centre positions | Holding cylinder in defined mid-position |
| ME (External pilot) | 3/2, 5/2 | Separate pilot | Ex zones, differing control pressure |
Typical applications
Typical applications: Control of pneumatic linear actuators in handling and assembly machines; valve islands for flexible manufacturing cells; Ex-protection applications in painting and solvent plants (ME external pilot); bistable switching tasks with long hold phase in compressed air automation (KM impulse valves); special machine and plant construction.
