- Shock absorption control for vertical lifting mechanisms
- Packaging machine gripper positioning systems
- Medical equipment actuator speed modulation
- Semiconductor handling robot end-effector controls
Installation guidance:
Mount downstream of cylinder ports using two wrenches - tighten base nut to 12-15N·m while holding body stationary.
For vertical installations, orient adjustment knob upward to prevent debris accumulation.
Perform final flow adjustments under system pressure for optimal calibration.
