Precision-engineered throttle valve featuring progressive needle adjustment for smooth speed control in both directions. The dual-scale indicator (0-10 gradations) enables repeatable settings, while the stainless steel spring ensures consistent performance under cyclic loading. Optimized for low-speed stability in pneumatic circuits requiring exhaust-side flow regulation.
- Cylinder speed synchronization in assembly lines
- Damping control for vertical load actuators
- Packaging machine gripper positioning systems
- Textile machinery tension control mechanisms
- Semiconductor wafer handling robots
Installation note:
For optimal performance, install within 300mm of cylinder ports. Use clockwise rotation for flow reduction.
Lubricate with ISO VG32 turbine oil if operating below -5℃. Avoid overtightening – maximum torque 1.2N·m.
