FlowCon SM 50-150mm, 2”-6”
Figure 1
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 for double flange
connections, i.e figure 1.
O-rings are supplied with the valve body and
are used to seal the connections. Pls. make
sure these are in place in the o-ring grooves
in the inlet and outlet of the valve body, when
installing the housing.
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.
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
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 2 next page).
