The FlowCon Green.3 valve is female/female
threaded and comes in two different sizes:
• FlowCon Green.3 DN40 (1½”)
• FlowCon Green.3 DN50 (2”)
IMPORTANT: Do not disassemble. The
FlowCon Greeen.3 is built as a complete valve
and only trained FlowCon personnel can per-
form repair. Unauthorized disassembly may re-
sult in calibration defects or damaged part and
will void warranty.

Setting and Installation
Prior to installing the FlowCon Green.3 (supplied
from factory in setting 4.5 due to calibration), the
system should be properly flushed. If it is not
possible to flush the system before Green.3 in-
stallation, please make sure to adjust setting to
5.0 (clockwise turning) and then flush.
The desired flow rate is hereafter set by adjust-
ing the valve (turn counter-clockwise to setting
1.0 and then clockwise up) with a special adjust-
ment key (i.e. figure 3/4). Range is between 1.0
and 5.0.
⚠
Do not overturn. Scale setting is
located on top of the valve numbered 1 to 5 in-
cluding in-between positions indicated by dots
(one dot for every 0.1 position). The specific po-
sition is defined by an indication mark on top of
the housing. Once flow is set, the required actua-
tor may be applied. Please see specific installa-
tion instruction for selected actuator.
A micrometer setting of 3.4 as illustrated in figure
4 corresponds to a maximum flow rate of: 2.86
l/sec (45.4 GPM).
