The Rain Bird 100HVFSS HVF inline valve is a professional-grade 1" irrigation valve with built-in flow control, designed to give installers precise zone balancing and reliable long-term performance. Its rugged construction and easy serviceability make it ideal for residential and commercial sprinkler systems.

  • Integrated flow control: Pressure-assisted, easy-to-turn flow stem for fast field adjustments without tools, allowing accurate balancing between zones.
  • Electrical specs: 24 VAC solenoid; inrush current 0.290 A at 60 Hz; holding current 0.091 A at 60 Hz; coil resistance 70–85 Ω (40°F–110°F).
  • Hydraulic performance: Flow range 0.2–30 GPM and operating pressure from 15 to 150 PSI (1–10 bar) to suit common irrigation applications.
  • Durable materials: Buna‑N eccentric diaphragm for smooth closing and reduced water hammer; self‑cleaning 200 micron (90 mesh) pilot filter and stainless steel spring.
  • Service friendly: Four multi-tool bonnet screws, external bleed for flushing, and a compact profile that fits easily in standard valve boxes.
  • Connections: Slip x slip 1" PVC connections (model 100HVFSS) for straightforward installation in typical irrigation piping.
  • Applications: Ideal for turf, shrub and general landscape irrigation; works with standard 24 VAC controllers and common solenoid wiring.

Includes a technical specs PDF with dimensions, wiring diagram and replacement parts. For drip or low-flow systems under 3 GPM, install a 200‑mesh upstream filter. Always follow local electrical codes when wiring; consult the product manual for installation, troubleshooting and replacement part numbers.

Frequently Asked Questions

What electrical supply does this valve require?
Requires a 24 VAC irrigation controller. Solenoid inrush is 0.290 A and holding current 0.091 A; follow local wiring codes.
How do I adjust the flow on the 100HVFSS?
Turn the pressure-assisted flow stem clockwise to reduce flow and counterclockwise to increase it. Use fingers or a slot-head screwdriver.
Is an upstream filter required for drip or low-flow systems?
Yes. For flows below 3 GPM or drip applications, install a 200‑mesh (90 mesh/200 micron) filter upstream to prevent pilot blockage. This preserves reliable valve operation.
What maintenance does this valve need?
Periodic inspection and flushing via the external bleed, and occasional diaphragm cleaning or replacement. Check the pilot filter if performance drops.
