Precision exhaust-side flow control valve with graduated scale (0-5) for repeatable adjustments. Features dual-directional check valve bypass for unrestricted inlet flow and controlled exhaust flow. Integrated O-ring groove allows direct manifold mounting. Requires 40μm filtration for optimal performance.
- Cylinder speed regulation in automated assembly lines
- Pneumatic actuator damping control
- Packaging machine gripper timing adjustment
- Medical device pneumatic braking systems
- Textile machinery tension control
Installation guidelines:
Install directly at cylinder exhaust port for effective speed control.
Full counter-clockwise rotation opens flow completely. For vertical mounting,
position adjustment knob upward to prevent debris accumulation. Lubricate weekly
with ISO VG32 turbine oil if using non-lubricated air systems.
