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.

HN manual override - manual switching during commissioning or PLC failure, without tools
Port sizes G 1/8" to G 1/2" - KM 09 (G 1/8"), KM 10 (G 1/4"), M 05 (G 1/8"), M 07 (G 1/4"), M 22 (G 1/2")
12-230 V DC/AC - all common control voltages available
Valve island assembly (RF series) - RF 09/RF 10 intermediate, end and blanking plates, XLVK direct-mount plates
6-position valves (MS 18310/6) - compact multi-function valves for space-saving installation

TypeWayFunctionTypical use
M / MO (Standard)3/2, 5/2Monostable, spring NC/NOSingle/double-acting cylinders
KM / M (Impulse)3/2, 5/2Bistable, impulseEnergy-saving control, long hold phase
KM (5/3)5/3Bistable, 3 centre positionsHolding cylinder in defined mid-position
ME (External pilot)3/2, 5/2Separate pilotEx 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.
