Key Features

Total control

Farmers control 1-10 sections of boom and low horticultural sprayers, including; usage of pressure relief valve (PRV); proportional flow control valve; precision flow sensor; any motorised section control valves

Maintain consistent pressure

The 74V1 Slow Hold feature automatically holds the control valve at a minimum operating pressure when slowing at headlands or around obstacles

Multi-step control

Achieve smoother transitions with rate/speed flexibility across different nozzle sizes for each spray line. The 74V1 Sprayer Controller selects first, second or both spraylines to maintain optimal working pressure

Optional dump

Divert pump delivery back to the tank whenever the master switch or section values are switched off with our optional dump valve. This is highly recommended if using a diaphragm pump

Second sprayline

The optional second sprayline is activated automatically when the first spray line reaches maximum pressure. The benefits of second sprayline have been proven for over 15 years – ask us how

Pressure control sensor

Optimise spray application for every field with 74V1 Sprayer Controller sensors to provide a pressure read-out and pressure-based control of the slow hold and second sprayline functions
