Wet System Valves
Solution Tank Sump Valve
N94211-UN-15JAN14
A - Solution Tank Sump Valve
With user input, the solution tank sump valve controls different loading methods when using either the solution pump or a nurse tank pump. The solution tank sump valve is also used to close off the solution tank from the rest of the wet system in case repairs are required in the system.Opening and closing of solution tank valve is controlled electronically by the automated wet system.
Pressure Valves
N98843-UN-17SEP12
N99941-UN-17SEP12
N99942-UN-17SEP12
A - Bypass Pressure Valve
B - Eductor/Tank Rinse Pressure Valve
C - Agitation Pressure Valve
D - Boom Isolation Valve
Multiple pressure valves are controlled electronically by the automated wet system and direct the flow of solution once it exits the pressure side of the solution pump.The bypass pressure valve (A) directs flow to the solution tank when using the solution pump to load from a nurse tank.
The eductor/tank rinse pressure valve (B) directs solution to a venturi at the solution tank. This venturi creates the vacuum needed to draw solution from the eductor hopper into the solution tank. The eductor/tank rinse pressure valve also directs water from the rinse tank to nozzles inside the solution tank when the rinse function is selected.
The agitation pressure valve (C) regulates the amount of agitation inside the solution tank.
The boom isolation valve (D) is closed to allow for cleaning strainers and for boom air purge use (if equipped).
Side Quik-Fill Valve
N99943-UN-20AUG13
A - Valve Handle
Side 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.
Front Fill Isolation Valve
N98786-UN-12JUL13
A - Front Fill Isolation Valve
Front fill isolation valve (A) completes the connection between the front Quik-Fill valve and the solution tank and is controlled by a switch located next to the front Quik-Fill valve.Front Quik-Fill Valve
N102217-UN-16MAY13
A - Valve Handle
B - Cap
C - Switch
Front Quik-Fill valve completes the connection between the nurse tank and the front fill isolation valve.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. Move switch (C) to the on position to open front fill isolation valve and solution tank sump valve. Move switch to pull-on position to start pump in pull-on fill mode.
NOTE: Leave switch in on position when using push-on fill mode.
After filling procedure is completed, rotate handle back to the closed position as shown. Move switch to off position to close the front fill isolation valve (and solution tank sump valve when push-on fill is used) before disconnecting nurse tank hose from the sprayer or performing front fill air purge.
Eductor Sump and Rinse Valves
N98787-UN-11SEP13
A - Valve Handle
Eductor Sump ValveEductor sump 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.
N98788-UN-11SEP13
A - Valve Handle
Eductor Rinse ValveEductor 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.
Strainer/Flowmeter Shut-Off Valve
N101655-UN-11APR13
A - Strainer/Flowmeter Shut-Off Valve
Strainer/Flowmeter shutoff valve (A) allows the operator to close the pressure line when cleaning the pressure strainers or flowmeters. Closing the valve limits the amount of solution that will drain and reduces 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.
NOTE: Close strainer/flowmeter shutoff valve when filling sprayer using nurse system pump to avoid air being forced into boom.
Rinse Tank Sump Valve
N94226-UN-01SEP11
A - Suction Valve
Rinse tank sump valve (A) allows flow from rinse tank and is controlled electronically by the automated wet system.Rinse Tank Fill Valve
N99944-UN-17SEP12
A - Valve Handle
Rinse tank 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.
