"Oventrop makes it a particularly difficult because, because that used in the course of time different threads."
There are many radiators radiator thermostats Oventrop branded, but they are partly already a few years older and do not have the correct thread size, which are required for the cultivation of this automatic radiator thermostats.
Technical Specifications:
- Older Oventrop valves have the thread size M30x1,0
- Newer Oventrop valves have the thread size M30x1,5
- This automatic thermostatic radiator needed for mounting a valve thread of M30x1,5
Now, if you screw a new automatic radiator thermostat to a older Oventrop valve, then breaks one of the threads. One would, however, already noted at top screws that it does not fit. After the first turn, it is very difficult to move.
How can you determine the thread in advance?
Unfortunately, this is not easy for a non-specialist.
Simply stated: The 1.0 and 1.5 are for spacing between the individual turns of the screw in mm. With a ruler or protractor could measure the distance of the thread turns on the Oventrop valve. If this is too insecure, easily compare the thread of the new radiator thermostats with the thread of Oventrop valve. The difference can be seen.
Apply When mounting under any circumstances violence; if it can be difficult to turn, something is wrong.
To solve this problem well in advance, there is threaded adapter M30x1,0 M30x1,5 on. Simply looking at Amazon for Adapter Oventrop.
