Installation
Ensure that the control valve is only used with one
of the diaphragm pump models listed in the
Features and Specifications section so that the
pressure and flow characteristics are compatible.
Initial Start Up
When starting the sprayer for the first time after
fitting a control valve, conduct a trial using clean
water only (no chemicals) to familiarise with the
operation of the control and to check that all
systems are functioning correctly without leaks.
Two Outlet and Three Outlet Ball Type control
valves can be mounted either directly to the pump
or in a remote location using the optional mounting
bracket kit. Three Outlet Flip Lever control valves
and Four Outlet valves must be mounted remotely.
Attach the sprayer to the tractor and carry out any
necessary
lubrication
and
adjustment
in
accordance with the sprayer Operator’s Manual.
Check the oil level of the diaphragm pump and if
necessary top up with SAE 20-40 multigrade
engine oil. Refer to the pump Instruction Manual
for further details.
To mount the valve directly to the pump, plug the
valve inlet connector into the pump outlet and
secure with the ‘U’ clip provided with the pump.
Attach a 13mm dia. (1/2”) pressure hose to each
valve outlet and connect to the spray boom
sections, or other spraying device if applicable.
Run a hose of specified diameter from the by-pass
outlet of the valve to the bottom of the tank to
return by-passed solution and provide agitation for
the contents of the tank. Refer to the Features and
Specifications page for the by-pass hose diameter
applicable to each valve. Always use the by-pass
connector supplied with the control valve never
replace it with one of smaller diameter. Secure all
hoses with worm screw clamps.
Check that the drain valve is closed and that all
strainers and filters are clean and in place, then
partially fill the tank with water and set the controls
so the sprayer will start without pressure in the
system, as described below.
General Operating Procedure
The general operating procedure is common for all
control valves. Refer to later pages for specific
information on each type.
Before engaging the PTO, the by-pass control
should be moved to the by-pass position and the
outlet valves should be closed, using either the
individual valve levers or the single lever,
depending upon control type.
To mount the control valve away from the pump
using the optional remote mounting kit attach the
mounting bracket in a suitable location and fit the
special inlet connector to the valve. Mount the
control valve by placing the inlet connector in the
bracket and secure it with the ‘U’ clip provided in
the kit. Plug the special outlet connector into the
pump outlet and secure with the ‘U’ clip provided
with the pump. Connect the pump outlet to the
control valve inlet using a suitable length of 19 mm
(3/4”) diameter pressure hose. Fit the outlet and
by-pass hoses as described above.
Engage the PTO slowly and allow the sprayer to
run in by-pass mode. Once the pump is primed
increase the tractor speed to 540 PTO rpm.
The by-pass lever can then be moved to the
operating or pressure position and the pressure
can be adjusted by turning the regulator knob and
observing the reading on the gauge.
5
Installation and Operation
The diaphragm pumps listed in this manual are
designed to operate up to a maximum pressure
between 15 bar (218 psi) and 40 bar (580 psi)
depending upon the model - refer to the pump
identification plate and the Specifications page of
this manual for details.
By-pass hose
connection
By-pass
control
“A”
The pressure range used for boom spraying will
normally be between 1 and 4 bar, depending upon
the application rate and other factors - refer to the
calibration information supplied for the spraying
equipment. Higher pressures may be required for
other applications such as a hand held spray gun
on a long hose.
Outlet
valves
“C”
Open the required number of outlet valves to
commence spraying.
Moving the lever its full travel anti-clockwise directs
pressurised fluid to the boom, or any other spray
device connected to the system, and only the
overflow from the pressure control is recirculated
to maintain agitation within the tank.
System pressure is regulated by turning the knob
“B” and observing the reading on the pressure
gauge. Turning the knob clockwise increases the
pressure and turning anti-clockwise decreases
pressure.
With the sprayer running at operating pressure and
with all spraying sections open, check for any
leaks and tighten hoses as required.
Chemicals can now be added Refer to Chemical
Safety Precautions section of this manual.
Fluid is directed to the boom lines or other
spraying devices by the outlet valves “C”. The
outlet valves may be operated individually and are
open when the lever is in line with the direction of
flow and closed when across the direction of flow.
Two Outlet Ball Type Control Valve and
Three Outlet Ball Type Control Valve
The operation of both valves is the same. The
selection of either the by-pass or pressure mode is
controlled by rotary lever “A” - refer diagrams.
Moving the lever clockwise through its full travel
selects by-pass, which recirculates the full flow of
fluid from the pump to the tank via the agitator line.

APS 71 and APS 96 Pumps
The diaphragm pumps listed in this manual are
designed to be driven by a tractor PTO at a
maximum speed of 540 rpm. However, under most
boom spraying conditions, the tractor PTO speed
can be reduced (Minimum 400 rpm) and the pump
will still provide sufficient flow to suit the application
rate being used. This will save fuel and
unnecessary wear on the tractor and sprayer
components.

Installation and Operation
Three Outlet Flip Lever Control Valve
Before adding chemicals read and
follow the chemical manufacturer's
instructions and always wear the
recommended protective clothing.
The operation of this valve is identical to the Three
Outlet Ball Type valve described previously except
that the outlet valves are open when the levers are
vertically down and closed when vertically up, as
shown in the diagram on the previous page..
Chemical Safety Precautions
Single Lever Control Valve
Take care to avoid the spillage of chemicals or
mixed solution. Wear gloves, eye protection and
the recommended protective clothing whilst mixing
chemicals and filling the sprayer. Wash your hands
after mixing or filling if they have come into contact
with concentrate or mixed solution.
Operation of by-pass control “A” and pressure
regulator “B” is the same as that of the two and
three outlet controls previously described.
Fluid is directed to the spray lines or other spraying
devices by the four outlet valves, which may be
operated individually or as a group. The individual
valves are open when levers “C” are vertically
down and closed when vertically up.
Store unused chemicals and dispose of empty
chemical containers, unused solution and rinse
water in a safe manner and with correct regard to
the environment, as recommended by the
chemical manufacturer or relevant authority.
Raising the single lever ”D” and swinging it over to
the other side of the valve opens the flow to all
valves and swinging it back closes the flow.
Daily Cleaning Maintenance
Once the required outlets have been selected
using the individual valves, spraying may be
started and stopped by using the single lever.
At the end of each day partly fill the tank with water
and run this through the pump, valves and spray
lines to purge them of chemicals.
If you wish to stop spraying but keep the tractor
PTO running, close the single lever and move the
by-pass lever to by-pass mode, but do not leave
the tractor while the PTO is operating.
Rinse the tank through the top opening and empty
with the drain valve to remove powdered material.
Never leave chemicals in the tank that could settle
to the bottom and break into lumps that may block
filters or control valves.
