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 (sup-
plied 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 in-
stalling 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.
