Description
1、Compact design with reduced weight and versatile installation compared to conventional speed control valves;
2、Effectively regulates operational speed of pneumatic actuators and transmission of air pressure signals;
3、Features intuitive push-pull adjustment with superior control responsiveness;
4、Quick-adjust mechanism with precise flow control calibration;
5、Excellent flow characteristics with high sensitivity and fine-tuning capability;
6、Switchable exhaust throttle and intake throttle configurations compatible with various pneumatic actuators;
7、Nickel-plated brass surface enhances corrosion resistance and contamination prevention;
8、Integrated PT seal ring in threaded ports ensures leak-proof connection integrity.
Installation note:
Install downstream of lubricator when used in pneumatic systems requiring oil mist.
Forbid installation in environments with ethylene glycol-based lubricants.
Adjustments should be made with system pressurized at 0.3MPa minimum.

Precision flow control valve with reverse flow check function, featuring micrometer-style locking knob for stable flow adjustment. The exhaust throttle design enables smooth actuator deceleration control. Built-in dust shield prevents particulate ingress during adjustment.
Typical Applications:
- Cylinder speed regulation in automated assembly lines
- Vacuum cup release timing control
- Packaging machine gripper synchronization
- Textile machinery tension adjustment systems
- Semiconductor handling equipment
Installation note:
Install downstream of lubricator when used in pneumatic systems requiring oil mist.
Forbid installation in environments with ethylene glycol-based lubricants.
Adjustments should be made with system pressurized at 0.3MPa minimum.
Maintenance:
Flush with filtered air monthly in high-usage scenarios.
Replace O-rings every 500,000 cycles or 2 years (whichever comes first).
Use only compatible grease (AirTAC PG-01 specified).
