FlowCon SM 50-250mm, 2”-10”
DYNAMIC SELF BALANCING
CONTROL VALVE
Install the FlowCon SM valve either in the supply or return pipework 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 for double flange
connections, i.e figure 1.
O-rings are supplied with the valve body and
are used to seal the connections. 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.
FlowCon SM.6 (200-250mm) contains two
o-ring grooves (figure 2). Sealing is done on
smallest diameter groove if 200mm flanges
are used and on the largest diameter groove if
250mm flanges are used.

silicone grease before installation.
IMPORTANT: Never use mineral oil or petrol
based grease or oil on the o-rings.
Valve bodies are as standard supplied with
pressure/temperature fittings (p/t plugs).
Before finger mounting the p/t plugs in the
body tappings, please seal the threads of the
p/t plugs (DO NOT OVER TIGHTEN).

Fitting and orientation of the actuator
To fit the actuator on the valve body, please
grease the o-ring on the spindle adaptor and
place the spindle adaptor on the valve spindle.
Place the actuator on the spindle adaptor and
place the three actuator “legs” into the three
holes in the mounting bracket. Make sure
that the snap ring is clicked onto the mounting bracket, so that the snap ring is locked at
the top of the mounting bracket, but is able
to rotate. Then turn the snap ring counter
clockwise (upside view) approximately 1/6 of
a turn until its stop points touch the actua-

tor “legs” and the mounting is locked with
a (small) click (please see figure 3 and 4).
To remove the actuator, please reverse the
procedure, i.e. turn the snap ring clockwise
until the actuator is loosened and lift the actuator up (fig. 5). To ease removal of actuator,
make sure that the valve is not fully closed.
Symbols at the bottom side of the actuator
also indicate how to lock and unlock the actuator with the snap ring.

• Valve is calibrating to determine closing point.
This calibration can take up to 10 minutes
depending on the valve’s position at start-up.
During calibration lower part of display will
show “CAL”.
• If no control signal is detected, flush is start ed if enabled in programming menu (enabled
by default), opening valve to 5/6 of fully open.
Lower part of display will show “FLUSH”
until control signal is detected.
• When control signal is present, actuator will
adjust to current control signal and proceed
with normal operation.
At first start-up please enter programming
menu to adjust actuator settings.
