Precision exhaust-side flow controller with bubble-tight shutoff capability, designed for precise cylinder speed regulation in pneumatic systems. Features 270° adjustable knob with click-stops for repeatable settings and anti-vibration locking mechanism. Includes built-in check valve for free reverse flow.
- Pneumatic cylinder speed stabilization in SMT equipment
- Vacuum generator exhaust flow optimization
- Medical bed actuator control systems
- Automated conveyor braking mechanisms
- Textile machinery tension control
Installation note:
Always install on cylinder exhaust port for speed control. For bidirectional control,
pair two units in parallel. Lubricate monthly with ISO VG32 turbine oil in high-cycle applications.
- Loosen lock nut by rotating counterclockwise
- Turn knob clockwise to decrease exhaust flow (slower movement)
- Turn counterclockwise to increase flow (faster movement)
- Retighten lock nut while holding knob position
