Precision throttle valve optimized for exhaust flow control in pneumatic systems. Features micro-adjustment knob with 4-step torque progression for fine speed tuning. The integrated check valve allows free reverse flow, enabling independent control of cylinder extension/retraction speeds. Chrome-plated adjustment screw resists corrosion in humid environments.
- Pneumatic cylinder speed synchronization in assembly lines
- Damping control for vertical cylinder applications
- Packaging machine stopper cylinder adjustment
- Textile machinery tension control systems
- Medical bed actuator speed regulation
Installation note:
Install within 500mm of cylinder ports for optimal response. Lubricate with ISO VG32 oil
if using non-lubricated air. Adjust while observing actual motion - clockwise rotation
reduces exhaust flow by 15% per 1/8 turn.
