Precision-engineered throttle connector featuring a locking nut design for stable flow control. The integrated check valve prevents reverse flow while allowing unrestricted airflow in forward direction. Calibrated adjustment knob with 0–100% graduated scale enables micron-level flow tuning. Compatible with ISO 15407-1 pneumatic systems.
- Cylinder speed regulation in SMC-type actuators
- Vacuum generator flow control
- Pneumatic gripper motion smoothing
- Air motor RPM adjustment
- Medical gas flow management systems
Installation protocol:
Install vertically with flow arrow aligned to system direction. For stable control:
(1) Loosen locknut (2) Rotate knob clockwise to reduce flow (3) Tighten locknut at 0.7–1.2N·m torque.
Use thread sealant on male ports only.
