Function:
The Oventrop radiator lockshield valves "Combi 4, 3, 2 and C"
are installed in the return pipe of the radiator. When installing
"Combi 4, 3 and C", please ensure that the draining facility for
draining the radiator is accessible. This will allow the removal of
radiators without the necessity to drain the system.
To carry out the hydronic balancing with the heating system, a
presetting can be made to alter the flow resistance.
Draining and filling of the radiator ("Combi 4, 3 and C" only) is
carried out using the service tool.
Application:
- Hot water central heating systems
- Chilled water circuits
"Combi 4 and C" radiator lockshield valve with the following
functions:
- Presetting with memory position
- Isolating
- Filling
- Draining
"Combi 3" radiator lockshield valve with the following functions:
- Presetting
- Isolating
- Filling
- Draining
"Combi 2" radiator lockshield valve with the following functions:
- Presetting
- Isolating
Note:
When using compression fittings, the Oventrop radiator lock-
shield valves can also be used in installations with Oventrop
composition pipe "Copipe" (14 and 16 mm) as well as copper
pipe (10-22 mm). The models with G
used for precision steel, stainless steel and plastic pipes as well
as the Oventrop composition pipe "Copipe".
Press connection:
For the direct connection of copper pipes according to DIN EN
1057/DVGW GW 392, stainless steel pipes according to DIN EN
10088/DVGW GW 541 and thin-walled C-steel pipe(material no.
E 195/1.0034) according to DIN EN 10305-3. Pressing must be
carried out to tighten the connection. Only use press jaws with
the original contours SANHA (SA), Geberit- Mapress (MM) or
Viega (Profipress) in corresponding size.
Processing must be carried out according to the installation
instructions.
