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.

recommended to grease the o-rings with a

It is
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-

The bottom side of the actuator

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.

Start-Up sequence

When power to the actuator is turned on, the
actuator will automatically calibrate:

• 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.

simultane-

ously for 6 seconds to start the auto-stroke.

Auto-stroke sequence

(display shows: “AUTO STROKE CYCLES”):

1. Valve is closed to determine closing point.

2. Valve is opened fully (independent of max.
flow chosen).

3. System returns to normal operation.

If actuator is not able to open valve fully, an
error will be displayed. An auto-stroke cannot
be cancelled.

Manual override

Manual override is used to temporarily set the
position of the valve regardless of the settings
and control signal for the actuator.

1. Turn off power to the actuator.

2. Remove actuator from valve as described.

3. Turn spindle to the relevant position (Clock­ wise to close valve, counter clockwise to
open valve). Be sure not to use more than
10 Nm torque. Please protect actuator from
water while not on valve.

4. Re-mount actuator on valve as described.

5. Turn on power to the actuator when normal
operation is needed.

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.

Do not remove cover from actuator. Opening
cover will void warranty.

When manually operating the valve (actuator
disconnected) do not use more than 10 Nm
torgue. Using more than 10 Nm torgue will
void warranty.
