Precision throttle valve with integrated check valve for bidirectional flow control in pneumatic systems. Features laser-etched flow scale (0-5 rotation steps) and anti-vibration lock nut. The blue anodized body ensures corrosion resistance and visual status indication.

Typical Applications:
  • Cylinder speed regulation in automation lines
  • Pneumatic gripper actuation timing control
  • Vacuum generator flow adjustment
  • Medical device pneumatic circuit balancing
  • Packaging machine air cushion damping systems
Installation note: Install with flow arrow aligned to desired direction. For optimal performance, complete 3-5 full open/close cycles before final adjustment. Lubricate threads with PTFE tape for leak-proof sealing. Max tightening torque should not exceed 0.8 N·m to prevent body deformation.
