Airtec solenoid valves
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.

| 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: 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.
