Brand: Hafner
SKU: Solenoid Valves - 5/2-way valves | Hafner

Hafner 5/2 Electromagnetic Valves

Hafner 5/2 valves are used for controlling double-acting pneumatic cylinders. The 5-port, 2-position configuration enables switching supply and exhaust between both actuator sides, providing controlled movement direction. The range includes inline valves, G-series, and manifold plate versions for modular installations.

Technical Variants

MMD10: M5 or Ø4 tube, flow rate 230 l/min, pressure 3–8 bar, single or double solenoid, 0.6 W coil consumption.
MD16: M5, Ø4, G 1/8” or Ø6, flow 280–450 l/min, pressure 3–10 bar, single or double solenoid.
MH inline: G 1/8” to G 3/4”, flow 650–6000 l/min, pressure up to 10 bar depending on type.
MEH: External pilot supply, suitable for low or fluctuating main line pressure.

Single vs Double Solenoid Operation

Single solenoid 5/2 valves return to a predefined position via spring or pneumatic return when the signal is removed. Used where a known safe position is required.
Double solenoid 5/2 valves have two coils and retain the last position until the next command. Applied where position memory or reduced continuous coil power is needed.

Selection Criteria

Selection is based on:

air flow relative to cylinder diameter and speed,
available line pressure,
single or double solenoid actuation,
connection type: M5, G 1/8”, G 1/4”, G 3/8”, G 1/2”, G 3/4”,
inline or manifold mounting,
requirement for manual override during commissioning.

Industrial Applications

Suitable for packaging machinery, assembly lines, pneumatic grippers, pushers, lifting devices, and automation panels with multiple actuators. Compatible with filtered, lubricated or non-lubricated compressed air.

FAQ

When is external pilot supply used?
When main line pressure is insufficient for reliable shifting or when control logic requires independent pilot supply.

What is checked during maintenance?
Leakage at exhausts, correct coil voltage, air cleanliness, silencers, and connection integrity.
