RK-20B – 1/2" Plastic Butterfly Mini-Sprinkler with 5/32" Nozzle
The RK-20B is a compact, spinner-driven butterfly mini-sprinkler designed for under-tree and low-profile irrigation in orchards, nurseries, and row crops. Its full-circle spray pattern delivers uniform water distribution across a 19–21 ft. radius at operating pressures as low as 14 PSI. The 5/32" nozzle provides a mid-range flow rate in the RK-20 series.
Key Features & Benefits
- Butterfly spinner design — creates a wide, uniform spray pattern ideal for under-canopy coverage without wetting foliage
- Low-pressure operation (14–28 PSI) — reduces energy costs and works well on gravity-fed or low-pressure systems
- 5/32" nozzle — mid-range flow option in the RK-20 series, delivering 2.2–3.2 GPM for balanced coverage and application rate
- Full-circle coverage — 19–21 ft. throw radius provides effective coverage for typical orchard and nursery spacing
- 1/2" MNPT connection — threads directly onto standard risers and poly tubing fittings
- Lightweight plastic construction — resists corrosion, UV degradation, and chemical damage from fertigation solutions
Ideal Applications
Under-tree irrigation in citrus groves, nut orchards, vineyards, and nurseries. Also suitable for greenhouse bench irrigation and low-growing row crops where overhead sprinklers would cause foliar damage.
