A: Yes, with the addition of a 500-ohm resistor.
🛒 Shopping Tips
- Verify valve compatibility (VG1000 Series) before ordering
- Confirm control signal type (voltage vs current)
- Check if plenum-rated cable is required for your installation
- Ensure torque rating matches your valve size/application
- Replace actuator if experiencing slow or failed valve response
