FlowCon SM 15-40mm
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
cover screw. Figure 3 illustrates the actuator
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).
