Pneumatically Actuated Valves

Product Information

Kuhnke pneumatically actuated valves have a compact design and can be used with low control pressures to switch between normally opened and normally closed position.

The pneumatically actuated valves series 46 works independently of supply pressure and switches operating pressures between 0 and 12 bar.

The miniature mechanically actuated valve series 72 was developed as extremely small pneumatic component, realizing high performance at common micro switch size.


  • Low space requirement (switch panel mounting)
  • High flow rates
  • Without overlap (types 46 and 74)
  • Diverse uses, e.g. buttons, catches, toggles, etc.


  • Appliances
  • Dental technology
  • Materials handling and process technology
  • Medical engineering
