Overview
The Festo RWN/O-3-1/8-B (part number 9694) is a reliable pneumatic limit valve widely used in industrial control systems. This valve features a lever actuator and 3/2 monostable operation, suitable for air control up to 8 bar. The valve has a normal nominal flow rate of 120 L/min and uses a G1/8 pneumatic working port. It is designed for precise pressure sensing and directional switching in pneumatic circuits.
Key Features
- 3/2 Monostable Operation: Open/closed function with monostable return
- Lever Arm Actuator: Manual actuation with positive mechanical action
- High Flow Capacity: 120 L/min nominal flow rate
- Compact Design: Space-efficient G1/8 port configuration suitable for manifold integration
- Pressure Rated: Suitable for pneumatic systems up to 8 bar operating pressure
- Mechanical & Hand-Operated: No electrical components required for actuation
