Precision throttle valve with integrated check valve for unidirectional flow control, featuring dual-scale flow indicators (0-10 adjustment marks with L/min reference values). The diamond-knurled knob provides secure grip even with oily hands. Requires 5-40μm filtered air and automatic drainage of condensate for optimal performance.
- Cylinder speed regulation in pick-and-place automation
- Exhaust flow control for pneumatic actuators in packaging lines
- Precision air cushion adjustment in semiconductor handling equipment
- Medical bed positioning systems requiring smooth deceleration
- Textile machinery tension control with vibration damping
Installation protocol:
Install directly on cylinder exhaust port using 0.1-0.3Nm torque.
For vertical mounting, orient adjustment knob upward to prevent debris accumulation.
Perform initial calibration with 50+ full rotation cycles before fine-tuning.
