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 directly at cylinder exhaust port for optimal performance.
Rotate knob clockwise to decrease exhaust flow (slower movement).
Use two wrenches during installation - 12mm on body flats and 17mm on adjustment nut.

Typical Applications:
- Pneumatic cylinder speed control in automation lines
- Packaging machine clamp force adjustment
- Conveyor system actuator synchronization
- Medical device pneumatic braking systems
- Semiconductor handling robot end-effectors
Installation note:
Install directly at cylinder exhaust port for optimal performance.
Rotate knob clockwise to decrease exhaust flow (slower movement).
Use two wrenches during installation - 12mm on body flats and 17mm on adjustment nut.
Maintenance:
Clean filter screen every 2,000 operation hours using compressed air.
Lubricate threads with silicone grease (ISO VG 1 grade) quarterly.
