Precision throttle valve featuring bi-directional flow control with integrated check valve functionality. The diamond-knurled adjustment knob provides tactile feedback during flow calibration, while the dual O-ring design ensures leak-free operation in dynamic pneumatic systems. Optimized for stable low-speed control down to 50mm/s cylinder speeds.
- Pneumatic cylinder speed regulation in SMT equipment
- Air cushion damping control in automation assembly lines
- Process gas flow adjustment in semiconductor manufacturing
- Packaging machine actuator synchronization
- Medical device pneumatic brake systems
Installation protocol:
Install vertically with flow arrow aligned to system direction. For precision adjustment:
1) Loosen lock nut
2) Rotate knob clockwise to reduce flow (5° increments = ~10% flow change)
3) Retighten nut while maintaining knob position
Use PTFE tape on male threads only, avoiding sealant contact with NBR components.
