The Rain Bird LFV100 is a 1" inline low-flow control valve engineered specifically for drip and xerigation zones. Its patented double-knife diaphragm and 1/2" seat handle particles at very low flow rates, preventing valve weeping and allowing reliable downstream filtration.

  • Designed for low-flow drip zones: Operates effectively at 0.20–8.0 gpm, ideal for micro‑irrigation and low‑flow control.
  • Patented diaphragm and seat: Unique double‑knife diaphragm with a 1/2" diameter seat ensures consistent on/off performance at low flows.
  • Reliable pilot design: Double‑filtered pilot flow plus internal and external bleed options for easy flushing and spray‑free manual operation.
  • Electrical compatibility: Standard 24 VAC solenoid (inrush ~0.30 A; hold ~0.19 A) for use with common irrigation controllers.
  • Filter placement flexibility: Handles particles at low flows so filters can be placed downstream of the valve when needed.

Use the LFV100 where precise low-flow zone control matters — drip lines, micro‑sprays, and xerigation applications. The inline 1" body fits standard irrigation piping and provides dependable, long‑term service when paired with proper system filtration and controller wiring.

Frequently Asked Questions

What flow range does the LFV100 typically support?
The LFV100 is built for low-flow zones and operates from about 0.20 to 8.0 gallons per minute, suitable for drip and micro‑irrigation.
What pressure and power requirements does it need?
Operating pressure range is approximately 15–150 psi and it uses a 24 VAC solenoid (inrush ≈0.30 A, hold ≈0.19 A) for standard controllers.
Can I place a filter downstream of this valve?
Yes. The LFV100’s diaphragm design handles particles at low flows, which allows safe downstream filter placement when needed.
