Precision exhaust-side flow control valve with progressive throttling characteristics, featuring dual-scale flow indicators (0-10 visual scale and L/min markings). The tapered needle design ensures linear flow adjustment with 3-stage damping stability. Includes anti-contamination check valve for reverse flow protection.
- Cylinder speed control in pneumatic actuators
- Damping adjustment for shock absorbers
- Vacuum system flow regulation
- Packaging machine ejection timing control
- Medical equipment pneumatic braking systems
Installation protocol:
Mount directly on cylinder exhaust ports using 35-45 N·m torque.
For optimal performance: 1) Purge air lines before installation
2) Adjust from fully closed position clockwise
3) Use locking nut after calibration.
Not recommended for use with synthetic lubricants.
