Frequently Asked Questions

What voltage does the 100-HV-NPT valve use?
The valve uses a 24 VAC solenoid (50/60 Hz). Inrush ≈0.290 A; holding ≈0.091 A; most standard controllers support it.
Can this valve be used for low-flow drip systems?
Yes—when a 200-mesh filter is installed upstream. For flows below 3 GPM the filter prevents pilot clogging and ensures reliable operation.
What thread type does the 100-HV-NPT have?
This model has 1" female NPT (F x F) threads. BSP and other fitting types are available in select configurations or as separate adapters.
How do I service or replace parts on an HV valve?
HV valves have an accessible bonnet and fewer screws for easier service. Use Rain Bird replacement parts and follow the included manual for step-by-step guidance.
