Raven has a control system to handle your liquid, granular, or NH3 needs. From one product to five, one boom to 10 - Raven has a system for you!

SCS 330, 440, 450, 660, and 661 controllers are automatic rate controllers that maintain a preset application rate as sprayer speed changes. SCS 700/710/750 chemical injection systems mix chemical (from undiluted chemical tanks) with a carrier (from a main tank) to apply a preset application rate while compensating for sprayer speed changes.

To determine the system components you require follow steps 1-6 below. Raven 330 and 440 system kits are also available that include console, flowmeter, control valve, and may include the speed sensor.

    RFM 60P - 1-60 GPM - Poly - 175 PSI - 1-1/2"(F)NPT
    RFM 60S - 1-60 GPM - SS - 500 PSI - 1-1/2"(F)NPT
    RFM 100 - 3-100 GPM - Poly - 150 PSI - 2"(F)NPT
    RFM 200 - 15 - 200 GPM - Poly - 90 PSI - 3" (F)NPT
    RFM 200C - 15 - 200 GPM - Cast Iron - 300 PSI - 3"(F)NPT
    RFM 400 - 25 - 400 GPM - Poly - 90 PSI - 4"(F)NPT
