Unique Diaphragm Design
Low Flow Valves
Valves designed exclusively for the low flow rates of a drip irrigation
system (0.2 - 10.0 gpm; 0.6 to 37.8 l/m)
Features
• The only valves in the industry made specically for drip irrigation
systems, making these the only valves that can eectively handle
particles at low ow rates – patented design
• These valves contain all of the features of reliable Rain Bird DV valves,
coupled with a unique diaphragm design that allows particles to pass
through at extremely low ow rates, thereby preventing weeping of the
valve
• Allows the lter to be safely placed downstream of the valve since these
valves handle all sizes of particles
• Unique “double-knife” diaphragm coupled with
1
⁄2" diameter seat for
awless operation at low ow rates
• Low Flow Valve is available in
3
⁄4" In-line model
• Double-ltered pilot ow design for maximum reliability
• External bleed to manually ush the system of dirt and debris during
installation and system start-up
• Internal bleed for spray-free manual operation.
Operating Range
• Flow: 0.20 to 10.0 gpm (0.6 to 37.8 l/m)
• Pressure: 15 to 150 psi (1.0 to 10.3 bar)
Electrical Specifications
