Precision exhaust-side speed controller featuring micro-flow stabilization technology, designed for precise cylinder speed regulation in bidirectional circuits. The tapered needle valve structure ensures smooth adjustment with 0.2 L/min resolution at low flow ranges. Integrated check valve allows free reverse flow, making it ideal for meter-out circuit applications.
- Pneumatic cylinder speed synchronization in assembly lines
- Damping control for vertical lifting mechanisms
- Packaging machine gripper positioning systems
- Medical bed actuator speed regulation
- Automated welding equipment stroke control
Installation guidelines:
Install closest to cylinder ports (within 500mm recommended). For vertical cylinders,
always use on cap side port. Lubricate weekly with ISO VG32 turbine oil when used
with non-lubricated air systems.
