Precision exhaust-side flow control valve with micrometer-style adjustment knob for fine-tuning cylinder speeds. Features anti-vibration locking mechanism and corrosion-resistant construction. The reverse-flow check valve design allows free flow in one direction while regulating exhaust flow in the opposite direction. Requires upstream lubrication or dry air compatibility confirmation.
- Cylinder speed synchronization in assembly lines
- Pneumatic actuator braking control
- Vacuum cup release timing adjustment
- Packaging machine clamp force regulation
- Die-casting machine ejection speed control
Installation note:
Install within 300mm of cylinder port for optimal response.
Use counter wrench during knob adjustment to prevent body rotation.
For vertical mounting, position adjustment knob upward to prevent debris accumulation.
