Proportional Valve Speed Control
Dynamic airflow regulation for high-speed pneumatic actuators
Flow Rate Modulation
Adjusts orifice opening via:
4–20 mA signals controlling air volume
Example: 50% opening → 1 m/s (50mm bore)
Pressure Gradient Control
Maintains precise inlet pressure:
Typical range: 2–6 bar
Balances force with exhaust flow to prevent overshoot
Dynamic Response Matching
Servo-proportional valves with:
LVDT sensors for real-time correction
Maintains speed within ±5% tolerance under load
Pulse Width Modulation
Rapid switching at 100 Hz for:
Smoother speed control than continuous throttling
Reduces heat generation by 30-40%
Exhaust Management
Integrated throttling controls:
Both extension and retraction speeds
30% port closure → 20% slower retraction
System Synchronization
Combined control enables precise velocity profiles:
- Trapezoidal acceleration curves
- S-curve transitions
- Vibration reduction up to 60%
