INSTALLATION AND OPERATION INSTRUCTION
FlowCon SM 15-40mm, 1/2”-1 1/2”
DYNAMIC SELF BALANCING
CONTROL VALVE
Install the FlowCon SM valve either in the
supply or return pipe work for the unit. It is recommended that a strainer be installed prior to
the valve body to prevent damage or blockage
due to debris. INSTALL THE VALVE HOUSING
WITH THE FLOW DIRECTIONAL ARROW
POINTING IN THE CORRECT DIRECTION.
The valve body is available with double union
end connections. Two types of end connections are available for use with the union nut:
Threaded (male or female):
The threads on both the connection and piping should be cleaned carefully.
As these models are union end connected, the
union nuts and the end connections should be
removed for installation.
O-rings are supplied with the valve body and
are used to seal the connections. It is recommended to grease the o-rings with a silicone
grease before installation. IMPORTANT: Never
use mineral oil or petrol based grease or oil
on the o-rings. Please make sure these are
in place in the o-ring grooves in the inlet and
outlet of the valve body, when installing the
housing and REMEMBER TO TIGHTEN THE
UNIONNUTS TO ENSURE SEALING.
Valve bodies are as standard supplied with
body tappings plugged, each plug sealed with
a gasket.
Alternatively, pressure/temperature fittings
(p/t plugs) are available. Before finger mounting the p/t plugs in the body tappings, pls. seal
the threads of the p/t plugs (DO NOT OVER
TIGHTEN).
Fitting and orientation
of the actuator
Pls. install the valve so that the actuator is
located upwards and not lower than the horizontal line to prevent condensation into the
electronics (pls. see figure 1 below).
Figure 1
Max 90º Max 90º
For all threaded connections pls. clear threads
on both valve and piping of debris. Sealant such
as pipe dope or teflon tape is recommended.
WHEN USING HEMP AS PIPE SEALANT,
ENSURE NO STRANDS ARE LEFT IN THE
VALVE OR PIPING.
Soldered end (sweat):
REMOVE THE END CONNECTIONS FROM
THE HOUSING BEFORE SOLDERING. THIS
ENSURES THAT THE O-RINGS AND INTERNAL PARTS ARE NOT DAMAGED BY HEAT.

Actuator wiring and programming
Remove the actuator cover by loosening the

circuit board layout and all relevant components when programming the actuator. Set
the maximum flow DIP switches (refer to table
on page 6). If adjusting the DIP switch settings after power has been connected, press
the reset button to input the new setting.
Figures 4-8 illustrate the different signal requirements, i.e. Analog 2-10V, Analog 4-20mA
and Digital Tri-state and how to apply
resistors and wires. Connect the wiring
according to the selected input signal.
500ohm resistors (the blue ones) are supplied
for 4-20mA to 2-10V conversion and connected
as illustrated in figure 4 (2-10V) or figure 5
(4-20mA).
Two 2.2Kohm resistors (the brown ones) are
supplied for special consideration for digital/
tri-state control. In this mode the actuator is
sensitive to induced electrical voltages from
other sources. To prevent such interference,
wire one 2.2Kohm resistor between pins 1 and
4 and the second 2.2Kohm resistor between
pins 1 and 3 (see figures 6 and 7).

The actuator is factory preset for an analog signal. If the signal requirement must be
changed, proceed with the instruction below:
Remove power and set all
programming DIP switches
to OFF.
Apply power and within 10
seconds, press and
release the reset button.
The programming and

This function applies to battery back up failsafe models only. It provides power storage to
drive the actuator either open to the maximum

power supply failure. As standard the actuator
is set to Failsafe Closed.
For Failsafe Open set

Actuator Zero and Span adjustment
Remove power from the actuator. Re-apply
power to terminal 2 and
within 10 seconds, press
and hold the reset button
until the indication LED

Release the reset button.
The indication LED should

Apply the new maximum voltage to terminal 3
(any value between 3 and 10VDC and at least
3VDC greater than the zero value).
Press and release the
reset button to memorize
this value. The indication
LED should blink once as
confirmation and then
cease to be illuminated.
The actuator will now operate with the new
zero value and span.
FAILURE: If the LED provides 3 sequences of
4 blinks, the zero and span programming was
unsuccessful. This may occur if the difference
between the zero and maximum voltages was
not equal or grater than 3VDC.
NOTE: The feedback signal will always be 420mA or 2-10V and independent of the zero

Circuit board diode
over-torque warning signal
Continual blinking indicates that the actuator
torque output limit has been exceeded.
This may have been caused by debris in the
valve internals. Disconnect power and manually operate the valve to clear the debris.
Re-apply power. The actuator will automatically recalibrate and reset. If the problem reoccurs, remove the valve body and check for
debris.
Manual over-ride operation
Remove actuator cover and DISCONNECT
POWER. Failure to disconnect power may
cause damage to the actuator gears. Fit the
manual over-ride key (FlowCon No. ACC0001)
onto the valve spindle. Press the clutch. Rotate
the manual over-ride key to open or close the
valve as required.

General
Water must always be suitable treated, clean
and free of debris. It is recommended that a
strainer be installed prior to the valve body to
prevent damage or blockage due to debris.
Ensure that the valve is not in the fully closed
position when filling the system with water.
Further, it is recommended not to exceed
maximum differential pressure control range.
Warranty obligation
Failure to abide by all recommendations as
per this installation and operation instruction
will void warranty.
