Precision exhaust throttle valve featuring dual-direction flow control with tactile feedback adjustment. The asymmetrical flow path design enables stable speed regulation for both cylinder extension/retraction motions. Equipped with anti-dust rotary cap and position memory function. Optimal for systems requiring differential speed control in opposing directions.
- Pneumatic cylinder speed synchronization in assembly lines
- Damping control for vertical load cylinders
- Packaging machine gripper positioning systems
- Textile machinery tension adjustment mechanisms
- Automated door soft-closing systems
Installation protocol:
Install directly on cylinder ports using 40cm maximum tubing length.
For vertical cylinders, position below actuator to prevent condensate ingress.
Perform initial calibration at 0.3MPa pressure with full clockwise rotation
before fine-tuning. Replace seals every 500,000 cycles in high-humidity environments.
