Precision exhaust-side flow control valve featuring bi-directional free flow and adjustable exhaust restriction. The chrome-plated brass construction ensures corrosion resistance in humid environments. Integrated check valve prevents reverse flow interference, while the knurled aluminum knob allows tool-free adjustment even with gloves. Requires 5μm filtered air for optimal performance.
- Cylinder speed regulation in automated assembly lines
- Pneumatic actuator damping control
- Packaging machine gripper synchronization
- Textile machinery tension control systems
- Semiconductor handling equipment vibration reduction
Installation note:
For consistent performance, install within 500mm of cylinder ports.
Rotate knob clockwise to decrease exhaust flow (slower movement).
Perform initial calibration at 0.5 MPa with 3 full open-close cycles.
