X20 Sprayer Reference Manual
Problem 19
Rate and Pressure do not match unless whole Boom is ON
Information
The Sprayer software is capable of controlling systems that use Bal- anced Valves. These valves are used by Hardi, and need to be ad- justed regularly. These valves, when closed, bypass the flow from the Boom Section back to the tank. This bypass flow is adjustable. The idea of the system is to maintain Sprayer pressure when turning the booms off or on. In a normal system, when a boom is turned off, the Sprayer is working with a lesser width, and the regulator reduces the pressure to maintain the flow rate for the remaining Sprayer width. This can affect the nozzle performance and thus the effectiveness of the Sprayer. With a balanced valve system, the pressure is maintained and thus the spray pattern.
In the X20 Sprayer Program, when Balance valves are ticked, the Flow Meter pulses are reduced by the proportion of the boom that is turned off. Control is still maintained, and if the valves are balanced properly, the pressure will not change with any variation in which booms are operating.
If the Balanced valve option is ticked WITHOUT balanced valves fitted, the pressure will rise when a boom is turned off. If it is NOT ticked with balanced valves fitted, the pressure will drop excessively when a boom is turned off.
