Precision exhaust-side flow control valve with integrated bypass check valve, featuring micro-precision throttling adjustment (360° rotating knob with click-stops). The chrome-plated brass construction ensures corrosion resistance in humid environments. Designed for smooth speed control of pneumatic cylinders during extension/retraction strokes.
- Pneumatic cylinder cushioning adjustment
- Conveyor belt synchronization systems
- Packaging machine clamp speed regulation
- Automated assembly line actuator control
- Textile machinery tension adjustment
Installation guidance:
Install directly on cylinder exhaust ports with arrow indicating airflow direction.
For optimal performance, use with 5μm filter and perform initial "full open" adjustment
before fine-tuning. Avoid overtightening - maximum torque 0.5N·m.
