Manual override valve with roller-lever mechanism for precise tactile control in pneumatic circuits. Features zero-power operation and failsafe spring return, with brass construction resisting hydraulic oil and mild chemicals. Optimized for repetitive manual actuation in harsh environments.
- Emergency stop systems in assembly lines
- Jig clamping control in CNC machining centers
- Manual override for automated packaging systems
- Safety door interlocks in industrial ovens
- Pneumatic fixture controls in automotive testing rigs
Installation note:
Lubricate lever pivot monthly with ISO VG32 pneumatic oil.
Ensure lever has 30° minimum clearance for full stroke.
Use PTFE tape on ports with clockwise tightening (15-20Nm torque limit).
