Dose control

Pneumatic valve, main valve and pneumatic section valves

The sensor on the chessis scans the sprayer's speed, the flowmeter measures the amount of liquid going through and the operating personnel controls the nozzle pressure on a glycerin pressure-meter. In case of deflection from the set dose the computer sends a signal to change the pressure over the regulation valve which is able to change the pressure on the nozzle from 0 to 10 atm in 5 seconds.

  • the fastest system of dose control in relation to the change of sprayer's speed
  • all the pneumatic valves are made of stainless steel and durable plastic material, electronic controlling items are inside the cabine - long service life
  • stainless control cabinet, can be unplugged from the sprayer
  • easy maintenance and servicing
  • manual, automatic and automatic with GPS

Pneumatic spraying regulation is easy, quick and reliable. It can withstand pressure of 9 bars long term and thanks to that it is possible to spray with higher pressure with low drift spray nozzles so the drops have a higher speed and are not too coarse. It works without problems with aggressive liquid fertilisers, its durability is not lowered in any way. Due to compressibility of air the regulative valve works as a pressure relief valve as well. Therefore there are less hoses at the sprayer and the washout of all the piping is much easier. Other big advantage is that there is no need to add antifreeze for winter, drainage to “dryness” is very easy thanks to pneumatic spraying regulation.
