Precision exhaust throttle valve optimized for air cylinder speed regulation in both directions. Features dual-scale flow indication (0-5 and 0-10 gradations) with torque-limited adjustment knob to prevent over-rotation. The graphite-enhanced seals provide extended service life under cyclic loading conditions.
- Pneumatic actuator speed control in automated assembly lines
- Vacuum generator flow regulation in packaging systems
- Medical bed positioning mechanism adjustment
- Textile machinery tension control systems
- Semiconductor handling equipment
Installation guidelines:
Install with arrow marking aligned to cylinder exhaust direction.
Use with 5-40μm filtered air. For optimal performance, perform
monthly knob rotation maintenance (full clockwise/counter-clockwise
turns to prevent seal sticking).
