Precision exhaust-side flow control valve designed for precise speed regulation of pneumatic cylinders. Features micro-adjustment capability (±5% repeatability) with visual scale indicator (0-10 gradations). Built-in check valve prevents reverse flow interference. Optimal for applications requiring smooth deceleration and position control.
- Pneumatic cylinder end cushioning adjustment
- Conveyor synchronization systems
- Automated assembly line positioning devices
- Textile machinery tension control
- Medical bed actuator speed regulation
- Packaging machine gripper timing adjustment
Installation guidelines:
Install directly at cylinder exhaust port for optimal responsiveness.
Maintain minimum 50mm clearance from heat sources. Perform initial
calibration at 0.5 MPa pressure. Lubricate quarterly with ISO VG32
turbine oil if used in dry air systems.
