Bi-directional flow control valve optimized for cylinder speed regulation, featuring a tamper-resistant locking collar and precision needle valve adjustment. The exhaust throttle design allows independent control of extending/retracting speeds in pneumatic cylinders. Corrosion-resistant construction with O-ring sealed adjustment knob.
- Precision cylinder speed tuning in assembly line automation
- Damping control for vertical load actuators
- Packaging machine gripper synchronization
- Medical equipment motion control systems
- Elevator door mechanism airflow regulation
Installation guidelines:
Install directly at cylinder ports using PTFE tape on threads. For exhaust throttling,
orient arrow marking toward cylinder port. Perform final adjustments under load with
0.2-0.3 MPa test pressure. Relock collar after tuning to prevent drift.
