The FlowCon EDP inserts are for use with
three different FlowCon valve housings, either:
FlowCon A DN15-25 (1/2”-1”)
FlowCon AB DN15-50 (1/2”-2”)
FlowCon ABV DN15-40 (1/2”-1 1/2”)
Insert Setting and Installation
Prior to installing the FlowCon EDP insert (sup-
plied from factory in setting 1.1 to facilitate as-
sembly), the system should be properly flushed.
Blank valve covers are available to be installed
during flushing.
It is recommended to grease the O-rings locat-
ed around the insert and headnut with silicone
grease before installing the insert in the valve
housing. After installation and if the side tapping
on the connector-ring is in the way, the connec-
tion-ring may be independently turned clockwise
for a more optimal position. Setting is better car-
ried out after the insert is installed in the valve
housing.
The desired ΔpC (controlled Δp circuit) is set by
adjusting the insert (turned from setting 1.0 and
up) with a special adjustment key. Scale setting
is located at the neck of the insert where the
white digits, numbered 1 to 5, indicate full turns
and the digits on the red counterwheel, num-
bered 0 to 9, indicate 1/10 of
full turn (
Figure 2 shows setting
4.2).
ΔpC can be measured
between Partner Valve (p/t
plug same sided as the ca-
pillary tube) and EDP (first
p/t
plug). Please wait until the
EDP has stabilized itself.
Capillary tube
Do not damage the capillary tube by compressing
or bending the tube with a bending radius below
20 mm (3/4”). Capillary tube is to be mounted us-
ing max. 0.1 Nm - DO NOT OVER TIGHTEN.
