Wet System Valves
Suction Valve
N81309-UN-15JAN09
A - Valve Handle
Suction valve allows the operator to select which tank the solution pump draws from. With valve handle (A) in position shown, the solution pump will only draw from the solution tank. Rotating valve handle to the opposite direction will close off the solution tank and allow the pump to draw only from the rinse tank. The valve is closed when the handle is straight up.Pressure Bypass / Rinse Valve
N81310-UN-15JAN09
A - Valve Handle
Pressure Bypass / Rinse valve allows the operator to direct the flow of solution once it exits the pressure side of the solution pump. With valve handle (A) in position shown, solution is directed to the spray boom for normal spraying operation.With valve handle rotated to the left, solution is directed to the rinse nozzles inside the solution tank.
With valve handle rotated to the right, solution is directed to solution tank when using the sprayer’s solution pump to load.
Quik-Fill Valve
N81312-UN-15JAN09
A - Valve Handle
Quik-Fill valve completes the connection between the nurse tank and the sprayer.Once the nurse tank hose has been connected to the machine, rotate valve handle (A) until parallel with plumbing to open the connection between the nurse tank and the sprayer.
After filling procedure is completed, rotate handle back to the closed position as shown before disconnecting nurse tank hose from the sprayer.
Solution Tank or Sump Valve
N84878-UN-09JUN09
A - Valve Handle
Sump valve allows the operator to select loading method.To spray or load the sprayers solution tank using a nurse pump, valve handle (A) must be in an open position.
The valve is placed in closed position for some loading and maintenance procedures.
Rotate valve handle (A) perpendicular to solution hose as shown to close valve.
Rotate valve handle parallel to solution hose to open.
Eductor Flow Rate Valve
N81313-UN-15JAN09
A - Valve Handle
B - Decal
Eductor flow rate valve allows the operator to direct solution to a venturi at the top of the solution tank. This venturi creates the vacuum needed to draw solution from the eductor into the solution tank.Rotate valve handle (A) to a horizontal position to create suction at the eductor.
Rotate valve handle back to a vertical position to stop suction as shown.
Decal (B) explains eductor flow rate valve functions.
Eductor Hopper Valve
N81314-UN-04SEP08
A - Eductor Valve Handle
Eductor hopper valve (A) allows chemical to be drawn from bottom of eductor hopper to top of solution tank.It is only operational when the eductor flow rate valve is open.
Eductor Rinse Valve
N81315-UN-04SEP08
A - Valve Handle
Eductor rinse valve allows operator to direct solution to rinse eductor hopper and rinse chemical containers.Rotate valve handle (A) to rinse.
It is only operational when the eductor flow rate valve is open.
Agitation Flow Rate Valve
N81316-UN-04SEP08
A - Valve Handle
Agitation flow rate valve allows the operator to regulate the amount of agitation inside the solution tank.Rotate valve handle (A) to create desired agitation in the tank.
For no agitation, rotate handle perpendicular to solution hose as shown.
NOTE: To minimize foaming run at lower agitation rate.
Turn off agitation when tank volume drops below 378.5 L (100 gal) to prevent foaming and air in system.
Orifice Valve
N81317-UN-08JUN09
A - Valve Handle
When applying low application rates, it may be necessary to turn orifice valve (A) to the closed (low) position.
If solution flow rate is greater than 100 Lpm (26 gpm) open orifice valve all the way, as shown.
See Applying Low Application Rates in SprayStar section for more information.
Boom Shut-off Valve
N81318-UN-08JUN09
A - Boom Shut-off Valve
Boom shut-off valve (A) allows the operator to close the pressure line to the boom. Closing the pressure line limits the amount of solution that drains and limits the amount of air introduced to the system.
To open, rotate handle parallel to solution hose as shown.
To close, rotate handle perpendicular to solution hose.
