Precision bi-directional airflow regulator with asymmetric control characteristics, featuring reverse flow free passage design for unrestricted inlet flow and precise exhaust-side throttling. The tapered needle valve mechanism enables 340° rotation with torque ≤0.3N·m for micro-adjustment capability. Includes dust-resistant rotary cap with click-stops every 15°.
- Cylinder speed synchronization in multi-axis systems
- Pneumatic gripper release timing control
- Vacuum breaker flow regulation
- Medical bed actuator speed adjustment
- Textile machinery tension control
Installation protocol:
Mount downstream of directional control valves with arrow aligned to exhaust flow path.
For vertical installation, orient adjustment knob upward. Perform initial calibration
by fully closing valve then opening 1/4 turn before fine-tuning. Lubricate quarterly
with ISO VG32 pneumatic oil.
