Precision bidirectional flow control valve featuring dual-path regulation with independent inlet/exhaust throttling. The swivel joint design allows 360° adjustment access in confined spaces. Chrome-plated brass construction ensures corrosion resistance in humid environments. Includes anti-vibration lock nut and graduated scale for repeatable settings.
- Pneumatic cylinder speed synchronization in assembly lines
- Exhaust flow control for shock absorption in pick-and-place systems
- Vacuum generator regulation in packaging machinery
- Air brake modulation in material handling equipment
- Process timing adjustment in semiconductor manufacturing tools
Installation protocol:
Apply thread sealant only on exhaust port side. Perform initial calibration
at 0.5 MPa with full counterclockwise rotation. For vertical downward flow
applications, install drip leg before valve. Re-lubricate every 500,000 cycles.
