Safety notes
2.1 Correct use
Safety in operation is only guaranteed if the valve is used correctly.
Oventrop double regulating and commissioning valves “Hydrocontrol
VFC/VFR/VFN/VGC“ are installed in hot water central heating and chilled
water A/C systems with a closed water circuit and serve to achieve a
hydronic balance between the various circuits of the system.
Any use of the valve outside of the above applications will be considered as
non-compliant and misuse. Claims of any kind against the manufacturer
and/or his authorised representatives due to damages caused by incorrect
use cannot be accepted.
The observance of the installation and operating instructions is part of the
compliance terms.
Heavy valve!
Risk of injury!
Suitable transport and lifting devices are to be used. Wear
suitable protective clothing (e.g. safety shoes) during installation and use
safety devices. External components like handwheels or pressure test
points must not be misused for the absorption of external forces, e.g. as
connection point for lever tools etc.
Hot or cold surfaces!
Risk of injury!
Do not touch the valve without safety gloves. It may get
very hot during operation.
Sharp edges!
Risk of injury!
Only touch with safety gloves. Threads, bore holes and
edges are sharp.
Small pieces!
Risk of ingestion!
Store and install the valve out of reach of children.
Allergies!
Health hazard!
Do not touch the valve and avoid any contact if allergies
against the used materials are known.
The case of an external fire has not been taken into consideration when
constructing the valve.

The double regulating and commissioning valves “Hydrocontrol VFC“
PN 16 and “Hydrocontrol VFR“ can be used for cold water up to PN 20.
Fluids:
Non-aggressive fluids (e.g. water and suitable water and glycol mix-
tures according to VDI 2035). Not suitable for steam or oily and aggressive
fluids. The bronze double regulating and commissioning valves “Hydrocon-
trol VFR“ can also be used for cold salt water (max. 38 °C / 100 °F) and
domestic water.
DANGER
Suitable measures (e.g. safety valves) have to be taken to ensure that the
maximum operating pressures and maximum and minimum operating
temperature are not exceeded or undercut.
