High-precision flow control valve featuring bi-directional exhaust throttling and a lockable rotary knob. The swivel joint design allows 360° orientation adjustment for flexible installation. Integrated debris-resistant needle valve mechanism maintains stable flow rates even in high-vibration environments. Requires upstream filtration (5μm recommended).
- Pneumatic cylinder speed regulation in automated assembly lines
- Exhaust air flow control for vacuum generators
- Damping adjustment in shock absorber cylinders
- Process gas flow modulation in food packaging machines
- Air motor speed control in handheld pneumatic tools
Installation best practice:
Mount vertically with exhaust port downward to prevent condensate accumulation.
Apply 243 thread sealant on male threads (do NOT use PTFE tape). Perform initial
adjustment at 0.5 MPa pressure for optimal calibration.
