SPRAYER APPLICATIONS

THE ELIMINATION OF VARIABLES

In order to achieve proper application with sprayers, as many variables

as possible must be eliminated.

With an unregulated sprayer the variables are:

1) pressure, 2) swath width, 3) flow rate and 4) spray pattern.

Pressure variation is no longer a factor with use of theG.A.T.E. Constant Flow Valve.

The flow rate is constant, regardless of pump pressure. The swath width and spray pattern are uniform with the CFValve™is installed.

The reduction of variables with CFValve™ installed reduces all variables.

The CFValve™ is a significant factor to quality application.

The region "EXCESSIVE PUMPING EFFORT" relates to the operator pumping at rates which are not sustainable over any period of time.

The region "SPRAY FINES & DRIFT" relates to production of spray particles that are prone to drift, and droplet spectrum that is typical at these flow rates and pressures.

The region "POOR SPRAY QUALITY" is when there is insufficient pressure to produce acceptable spray pattern from the nozzle.

Extensive field trials indicate that, in general, optimum pressure range application is 21 psi for the 1.45 Bar.

Thus the 1.45 Bar CFValve™ in the graph above maintains application pressure, i.e. flow, and will automatically close at insufficient pressure with no dripping or waste.

The "OPTIMUM ZONE" is unique to the CFValve™ and of significant value to targeted label applications.
