Pneumatically Actuated Valves
Control and Directional Valves
Pneumatically actuated valves from Riegler switch compressed-air flow via an applied pneumatic control signal rather than an electrical solenoid. The range covers 3/2-way valves in monostable form with spring return and bistable variants, available as normally closed (NC) or normally open (NO).
Port sizes span G 1/8 to G 1/2; bistable types are rated by nominal width (DN 5 to DN 15). With more than 85 items the series suits the build-up of purely pneumatic control chains without electrical components.
Monostable spring return to the initial position once the control signal drops.
Bistable holds the last switched position even after loss of the control-signal pressure.
NC / NO normally closed or normally open function depending on the switching task.
Ports G 1/8 to G 1/2 graded nominal width to match the required flow.
Pneumatically actuated directional valves are used in purely air-controlled systems, in hazardous areas where electrical switching is not permitted, and as an amplification stage for weak pneumatic control signals.
