Anti-vibration locking mechanism maintains set flow rate under mechanical shock. Includes built-in check valve for free reverse flow.
- Pneumatic cylinder velocity stabilization in SMT equipment
- Packaging line actuator synchronization
- Textile machinery tension control systems
- Automated door closing speed adjustment
- Food processing conveyor timing mechanisms
Installation note:
For optimal performance, install within 300mm of cylinder ports. Lubricate with ISO VG32 turbine oil
if used in high-cycle applications (>500,000 operations/month). Avoid mounting in downward-facing
orientation where debris could accumulate.
- Loosen lock nut by rotating counterclockwise
- Turn control knob: clockwise to decrease speed, counterclockwise to increase
- Test cycle 3-5 times after adjustment
- Tighten lock nut while holding knob position
