Precision flow control valve featuring twin-needle adjustment with lockable dials for independent meter-out control. The T-handle design allows tool-free adjustment with positive tactile feedback. Includes built-in check valve functionality and dust-resistant rotary mechanism. Requires ISO 8573-1 class 3 (5μm) filtered air.
- Pneumatic cylinder speed synchronization in SMT assembly lines
- Exhaust air flow optimization in plastic injection molding machines
- Damping control for automated material handling systems
- Precision actuator positioning in semiconductor manufacturing
- Packaging line gripper release timing adjustment
Installation note:
Mount within 500mm of actuator for optimal response. Use counterclockwise rotation
for flow reduction. Apply thread sealant only on male ports, avoiding contamination
of internal flow paths. Perform initial "full open" commissioning before fine-tuning.
