Air Consumption of Single-Acting Pneumatic Actuators
Single-acting pneumatic actuators are energy-efficient, consuming significantly less compressed air than double-acting models.
One-Way Air Demand
- Compressed air only required for one-direction movement (e.g., opening valve)
- Spring handles return stroke, eliminating air need during reset
Lower Air Volume per Cycle
- Uses 30-50% less air than double-acting actuators of same size
- Example: 6-bar actuator consumes 0.5-1.5 SCMH (varies by stroke/cycle rate)
Reduced Operating Costs
- Saves energy in high-cycle applications (water treatment, HVAC)
- Allows smaller compressors/reservoirs, lowering infrastructure costs
Comparison to Double-Acting Actuators
| Feature | Single-Acting | Double-Acting |
|---|---|---|
| Air Consumption | 30-50% less | Higher (air for both strokes) |
| Return Stroke | Spring-powered | Air-powered |
| Best For | Energy savings & fail-safe | High-speed cycling |
Ideal Applications
- Systems prioritizing energy efficiency
- Fail-safe critical operations
- Moderate speed requirements
- Cost-sensitive installations
