The FlowCon EVS plug-in insert is for use with
three different FlowCon valve housings, either
FlowCon A, FlowCon AB or FlowCon ABV1.
Install the selected valve housing as called for in
the design drawings. Although the performance
of the valve is not affected either way, industry
standards call for balancing devices to be in-
stalled on the downstream side of the terminal
unit. Especially for the ABV1 with its isolation
ball valve, it is recommended to ensure the iso-
lation valve is downstream of the balancing
device. INSTALL THE VALVE HOUSING WITH
THE FLOW DIRECTIONAL ARROW POINTING
IN THE CORRECT DIRECTION.
The FlowCon A valve (Model Nos. A15.X,
A20.X and A25.I.K) is available with fixed female-
by-female threaded connections, i.e. figure 1.
The thread standard for the A model is either
ISO 228, which is a straight metric thread
(compatible with BS-2779) or NPT threading
standard, depending on the product number
ordered.
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.
The FlowCon AB valve (Model Nos. AB15.X,
AB20.X and AB25.I.K) is similarly available with
fixed female-by-female threaded connections,
i.e. figure 2.
The thread standard for the AB model is equal
to what is available for the A model.
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.
Pressure/temperature fittings (p/t plugs) are
available upon request for the AB valve. Before
finger mounting the p/t plugs in the body
tappings, pls. seal the threads of the p/t plugs
(DO NOT OVER TIGHTEN).
Alternatively to p/t plugs, the valve body can be
ordered with plugs for the body tappings. Each
plug is sealed by a gasket.

Figure 3
The FlowCon ABV valve (Model No. ABV1)
is available with double union end connections,
i.e. figure 3.
Two types of end connections are available
for use with the union nut:
Threaded (male or female):
The thread standard is ISO 228 which is a
straight metric thread (compatible with BS-2779)
or NPT threading standard, depending on the
end connections ordered. The threads on both
the connection and piping should be cleaned
carefully. As these models are union end con-
nected, the union nuts and the end connections
should be removed for installation.
O-rings are supplied with the valve body and
used to seal the connections. It is recommended
to grease the o-rings with 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 UNION NUTS
TO ENSURE SEALING.
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 INTER-
NAL PARTS ARE NOT DAMAGED BY HEAT.
Pressure/temperature fittings (p/t plugs) are
available upon request for the ABV valve. Before
finger mounting the p/t plugs in the body
tappings, pls. seal the threads of the p/t plugs
(DO NOT OVER TIGHTEN).
Alternatively to p/t plugs, the valve body can be
ordered with plugs for the body tappings. Each
plug is sealed by a gasket.
Inserting the cartridge
The factory pre-set stainless steel flow control
cartridge is fitted into the EVS insert from the
bottom and is held in position by the lock ring
screwed onto the EVS insert.
It is recommended that the o-rings located
around the EVS insert, in the bottom and in the
middle, are lubricated with silicone grease, be-
fore the EVS insert is installed into the valve body.
IMPORTANT: Never use mineral oil or petrol
based grease or oil on the o-rings.
NOTE: When applying the flow control car-
tridge, please make sure that the cartridge o-
ring is placed on the inside groove at the top of
the EVS insert BEFORE inserting the cartridge!
Hereafter the cartridge is easily inserted with
a hard push. Once you hear a click sound, it is
properly placed and the cartridge is correctly
fitted. Screw on the lock ring and insert the EVS
insert into the valve body. The cartridge can be
removed by unscrewing the lock ring and pulling
out the cartridge. The cartridge o-ring will also
come out. Insert the new o-ring and afterwards
insert the new cartridge as described above.

FlowCon EV.0.2
Figure 5
Actuators:
The actuator types FlowCon EV.0.2, EV.0.3,
EV.0.4 and EV.0.5 (i.e. figure 5) are supplied
with a separate green colored adaptor nut. Use
this adaptor nut and screw it finger tight to the
connection thread at top of the EVS insert. Do
not use additional tools. The actuator can now
be fitted to the adaptor nut. A click noise will
indicate that the actuator is fitted into a correct
position.
The visor on the FlowCon EV.0.2 actuator is
used to activate a release mechanism and when
pushed, the actuator can be released and re-
moved from the adaptor nut. By removing the
visor after fitting the actuator, the actuator
becomes tamper proof. Similar for the FlowCon
EV.0.3, EV.0.4 and EV.0.5 actuators, these are
released by pushing the button in the front side
of the actuator and then removing the actuator
from the adaptor nut.
To ensure that the valve is in an open position
during commissioning of the system, all men-
tioned actuators will be delivered in a Normally
Open position and remain in this position until
they are electrically operated first time.
During FIRST TIME POWERING operating
voltage is applied for approximately 6 minutes.
Upside down installation is allowed for all
mentioned actuators along with the standard
horizontal and vertical installation.

General.
It is recommended flushing the system before
installing the cartridge in the valve body. Suitable
flushing caps are available. 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.
Warranty obligation.
Failure to abide by all recommendations as per
this installation and operation instruction will void
warranty.
