Hafner 3/2 Electromagnetic Valves

Hafner 3/2 valves are used for control of pneumatic signals, actuation of small single-acting cylinders, and exhaust functions. Each valve features three ports: supply, actuator output, and exhaust. MH series are normally closed, while MOH/MX variants are normally open, selected according to circuit fail-safe logic.

Technical Variants

MH 311 012 / 015: Direct-acting, M5 or G 1/8”, flow rate 40–50 l/min, pressure range -0.9…10 bar, coil consumption 3 W DC or 5 VA AC. Suitable for pilot signals, vacuum applications, and small actuators.
MH 311 305 / 309: Direct-acting with MA30 system, G 1/8” or G 1/4”, flow rate 200 l/min, pressure 0…7 bar, coil 7.5 W DC or 8.5 VA AC.
MH 310 / 311 G-series: Higher flow inline valves, from 650 l/min (G 1/8”) up to 3000 l/min (G 1/2”), max operating pressure up to 10 bar depending on model.

3/2 Valve Selection Criteria

Selection should consider:

Required actuator air flow
Available supply pressure
N.C. or N.O. fail-safe position
Connection thread: M5, G 1/8”, G 1/4”, G 3/8”, G 1/2”, or NPT
Coil voltage and connector type
Manual override requirements during commissioning

Industrial Applications

Applied in packaging machinery, assembly lines, pneumatic panels, vacuum handling, auxiliary automation commands, and circuits requiring simultaneous supply and exhaust of the actuator.

Maintenance and Leakage

Periodic inspection should verify air cleanliness, seat condition, exhaust leakage, correct coil voltage, and manual override operation. For dusty or humid environments, ensure appropriate air preparation upstream of the valve.
