Precision throttle valve featuring dual-function flow control with integrated check valve for one-way free flow. The knurled brass knob enables 300° rotation with torque ≤0.3N·m, offering tactile feedback for incremental adjustments. Nickel plating provides corrosion resistance in humid environments.
- Pneumatic cylinder speed regulation in automation lines
- Air tool exhaust flow control
- Vacuum system bleed air adjustment
- Medical device pneumatic timing controls
- Packaging machine actuator synchronization
Installation protocol: For meter-out control, install on cylinder exhaust port. Use thread sealant (LOCTITE 545) for NPT versions.
Adjust while observing actuator motion - clockwise rotation reduces flow. Perform locknut tightening after calibration.
