- Air brake modulation in material handling systems
- Pneumatic actuator synchronization in packaging machinery
- Process gas flow adjustment in semiconductor tools
Installation protocol:
Mount directly on cylinder exhaust ports using 12–15 N·m torque.
For optimal performance, install filter within 500mm upstream.
Rotate knob clockwise for slower exhaust (0–270° adjustment range).
Requires quarterly lubrication with ISO VG32 pneumatic oil.
