Hafner 5/3 Electromagnetic Valves

Hafner 5/3 valves are used for controlling double-acting pneumatic cylinders where a third, neutral position is required. Return to the center position is spring-actuated. Most variants include a manual override for circuit testing and commissioning procedures.

Center Position Variants

531 – Closed Center: All working ports are isolated. Applied where temporary position holding is needed, considering air compressibility and internal leakage.
532 – Exhaust Center: Ports 2 and 4 are vented. Suitable when the actuator must be depressurized upon signal loss.
533 – Pressure Center: Both sides of the cylinder are pressurized. Used in specific balancing or preloading arrangements.

Technical Specifications

The range includes MMD10 (M5 or Ø4, 230 l/min, 3–8 bar, 0.6 W). MD16 models are available with M5, Ø4, G 1/8” or Ø6, flow rates 280–450 l/min, 3–10 bar, 1.8 W / 3 VA. MH inline / G-series cover G 1/8” to G 3/4”, flow rates 650–6000 l/min, 3 W / 5 VA.

External Pilot and Installation

MEH versions use external pilot supply. Main line operates at 1–10 bar; pilot actuation requires 3–10 bar. Selected when main pressure is low, variable, or when safety logic demands independent pilot supply.

Typical Applications

Double-acting cylinders in packaging machinery
Grippers, pushers, and clamping stations
Pneumatic panels with manifold bases
Automation requiring controlled behavior on signal loss

Selection and Maintenance Considerations

Check flow rate, pressure, center position type, thread, coil voltage, connector type, and need for manual override. Note: For Hafner G-series, coil and electrical connector are not always included with the base valve. Consider leakage, media compatibility, and maintenance intervals per application standards.
