Pressure Relief
Sprayers fitted with the Raven Flow Regulator Valve and a Positive Displacement (Piston or Diaphragm) pump require the fitting of a Pressure Relief Valve to the Sprayer.
The Raven Fast Flow Valve switches to Dump when the sectional switches or Master switch are turned off. With the Topcon system this can make the time to obtain spraying pressure slow. To rectify this, a manual Pressure Relief Valve is fitted to the system which then allows rate to be achieved within 3 seconds.
The other benefit of fitting the pressure relief valve is that it will protect the system from over pressurizing, other pressure damage and the pos- sibility of hoses being "burst" off of their fittings. Fitting the Pressure Relief Valve will also prevent the operator from getting covered in chemical.
Fitting
WARNING WARNING
The Sprayer and Pump must be turned OFF and there must be zero chemical in the system, when fitting the Pressure Relief Valve.
Protective clothing, gloves and eyewear must be used when fitting the Pressure Relief Valve.
