INSTALLATION AND OPERATION INSTRUCTION
INSERT FOR PRESSURE
INDEPENDENT CONTROL VALVE
FlowCon Green 15-40mm
The FlowCon Green inserts are for use with three
different FlowCon valve housings, either:
FlowCon A (DN15/20/25),
FlowCon AB (DN15/20/25/32) or
FlowCon ABV (DN15/20/25/32/40).
Install the selected valve housing as called for in
the design drawings. Although the performance of
the valve is not affected either way, industry stan
dards call for balancing devices to be installed on
the downstream side of the terminal unit. Especially for the ABV with its isolation ball valve, it is recommended to ensure the isolation valve is downstream of the balancing device.
INSTALL THE VALVE HOUSING WITH THE FLOW
DIRECTIONAL ARROW POINTING IN THE COR
RECT DIRECTION.
The FlowCon A valve (Model Nos. A15.X, A20.X
and A25.I.K) is available with fixed female-byfemale threaded connections, i.e. figure 1.
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 (except
for DN25 which currently is only ISO).
WHEN USING HEMP AS PIPE SEALANT, EN
SURE NO STRANDS ARE LEFT IN THE VALVE
OR PIPING.
The FlowCon AB valve (Model Nos. AB15.X,
AB20.X, AB25.X and AB32.X) is similarly available
with female-by-female threaded connections, i.e.
figure 2.
Figure 2
The thread standard for the AB model is equal to
what is available for the A model.
For all threaded connections please 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,
please 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.
The FlowCon ABV valve (Model No. ABV1 and
ABV2) is available with double union end connections, i.e. figure 3.
For all threaded connections please clear threads
on both valve and piping of debris. Sealant such as
pipe dope or teflon tape is recommended.

INSERT FOR PRESSURE
INDEPENDENT CONTROL VALVE
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 connec
tions ordered. 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 used
to seal the connections. It is recommended to
grease the o-rings with silicone grease before in
stallation. IMPORTANT: Never use mineral oil or
petrol based grease or oil on the o-rings. Please
make sure the o-rings 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 please 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 EN
SURES THAT THE O-RINGS AND INTERNAL
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,
please seal the threads of the p/t plugs (DO NOT
OVER TIGHTEN).
Alternatively to p/t plugs, the valve body can be or
dered with plugs for the body tappings. Each plug
is sealed by a gasket.
Inserting the insert
Prior to installing the FlowCon Green insert (supplied from factory in setting 5.0 due to calibration),
the system should be properly flushed. A blank valve
cover is available to be installed during flushing.
It is recommended that the o-rings located around
the Green insert and at the headnut are lubricated
with silicone grease, before the insert is installed
into the valve body.
IMPORTANT: Never use mineral oil or petrol based
grease or oil on the o-rings.
The desired flow rate is chosen by adjusting the
flow control insert (turned from setting 1.0 and up),
with a special adjustment key, i.e. figure 4 (page
3). The key is used to adjust the scale on the top of
the insert; the large white numbers are numbered
1 through 5 and the red are numbered 0 through 9.
The insert can be installed in the valve body
either before or after setting the required flow
rate. Once the correct flow rate has been select
ed and the insert is fitted in the valve body, then
the actuator is applied.
Please see specific installation instruction for se
lected actuator.
General
It is recommended flushing the system before installing the insert 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 war
ranty.
