4V210-08 vs. 4V220-08: Choosing Single vs. Double Solenoid

System Logic: When to Use 4V210-08 vs. 4V220-08

Choosing between the single solenoid Airtac 4V210-08 and the double solenoid 4V220-08 depends on your safety and PLC logic requirements.

1. Power Consumption

The 4V210-08 requires constant power to stay in the energized state. The 4V220-08 only needs a momentary pulse to shift and will stay in that position until the other coil is pulsed.

2. Fail-Safe Behavior

If the power is cut, the 4V210-08 will automatically return to the home position via spring pressure. This is a vital safety feature for preventing machine collisions during a power outage.
