Precision throttle fitting with integrated flow control mechanism, featuring a unique spiral groove design for linear flow adjustment. The 45° conical sealing surface ensures zero-leak performance under vibration. Compatible with ISO 8434-1 standards for pneumatic systems.

Key Applications:

• Speed regulation of pneumatic cylinders in assembly lines
• Air cushion damping control in shock absorbers
• Precision air flow adjustment for medical analyzers
• Packaging machine actuator synchronization
• Robotic end-effector pressure balancing

Installation protocol: Cut tube ends square (max 0.5° bevel), insert fully until tube bottom-out, then tighten 1/4 turn past hand-tight. Perform flow calibration using clockwise rotation for reduced flow (max 270° adjustment).

Maintenance: Replace sealing elements every 500,000 cycles or 2 years (whichever comes first). Use AirTAC SPG-04 silicone grease for re-lubrication. Avoid IPA cleaning - use pneumatic line filters with 5μm rating.
