The Rain Bird LFV100 is a 1-inch inline valve designed to control drip irrigation zones with flow rates of 0.2–8 GPM. Its low-flow diaphragm helps prevent weeping, while the 24 VAC solenoid lets a compatible irrigation controller switch watering on and off.
Key Features
Double-knife diaphragm and 1/2-inch seat support low-flow operation.
Double-filtered pilot-flow path helps protect the operating passages.
Internal bleed allows manual operation without an external discharge.
External bleed provides a flushing option during installation and startup.
Normally closed electric valve with a standard 24 VAC solenoid.
Common Uses
Switching a low-volume drip irrigation zone on and off from a compatible controller.
Connecting a drip control assembly to matching nominal 1-inch male NPT fittings.
Technical Specifications
Model: LFV100; manufacturer part X12110.
Inlet and outlet: nominal 1-inch female NPT.
Flow range: 0.2–8 GPM.
Operating pressure: 15–150 psi.
Standard solenoid: 24 VAC, 50/60 Hz.
Inrush current: 0.30 A / 7.2 VA at 60 Hz.
Holding current: 0.19 A / 4.56 VA.
Maximum water temperature: 110°F / 43°C.
Maximum ambient air temperature: 125°F / 52°C.
Valve only; downstream filtration and pressure regulation are separate functions.
Dimensions
Rain Bird’s LFV technical sheet lists a 4-1/2-inch height, 4-3/8-inch length and 3-1/3-inch width. The nominal 1-inch FNPT ports describe pipe fit, not the overall valve size. Leave additional clearance above the bonnet and solenoid for wiring, manual operation and service.
Compatibility & Installation Notes
Match both 1-inch female NPT ports to the correct male fittings and follow the valve’s molded flow arrow. Flush debris from the supply before connecting the drip equipment. Size the zone for 0.2–8 GPM, account for pressure loss through the valve and filter, and check the downstream devices’ pressure requirements. Use a separate compatible filter and regulator as needed; this valve does not regulate pressure or provide anti-siphon backflow protection. Standard operation requires a compatible 24 VAC irrigation controller. A battery-operated system needs the specified latching-solenoid configuration rather than the standard AC solenoid. Shut off water and relieve pressure before servicing the bonnet or solenoid.

Frequently Asked Questions
What flow range does LFV100 support?
Use a zone flow of 0.2–8 GPM. Add the demand of every emitter and other watering outlet when sizing the zone.
What controller does the standard valve use?
The standard valve uses a compatible 24 VAC, 50/60 Hz irrigation controller. Battery-operated control requires the appropriate latching-solenoid configuration.
Does the valve include a filter or pressure regulator?
No. Select downstream filtration and pressure regulation separately to suit the drip devices and water supply.
Why Buy from Big Frog Supply?
Choose LFV100 for a 0.2–8 GPM drip zone with 1-inch pipe connections and a compatible 24 VAC controller. Its low-flow diaphragm helps prevent weeping, while internal manual bleed lets you operate the zone during setup or service. Add a filter and regulator matched to the downstream drip devices.
