HAFNER Pneumatik: Your expert for pneumatic valves for rail vehicles

HAFNER valves are well received in the railway industry because of their robust design and ability to work in low temperatures down to -50°C. No matter if for train door controls, train couplings or wagon construction – HAFNER has the right solution!


Some technical features make HAFNER valves especially valuable in railway applications:


  • Solenoid systems with a voltage tolerance of +/- 30% in railway-typical voltages Applicable for an ambient temperature as low as -50°C
  • Robust design
  • High flow with compact design
  • Maximum sealing efficiency at low pressure
  • Solenoid valves with up to IP67 protection


Train door control

Combination of a solenoid and pilot- operated valve. Used for train door controls in Switzerland.

Valves for train coupling systems

Mechanically and electrically operated valves used in train coupling systems. Valves operate a double-acting cylinder which moves a power box during the coupling process and thereby establishes a power-supply connection between two wagons.
