DANFOSS RA-N 15 Thermostatic Valve, Straight
Pre-setting valves are used in two-pipe central heating systems. They ensure optimal water flow distribution in the heating system. The pre-setting function allows for precise adjustment of the calculated flow. No tools are required for pre-setting.
The thermostatic valve can be used with all RA 2000 and RAW series thermostatic heads and TWA-A actuators.
Can be used with side-connected radiators or convectors from all manufacturers. It can also be used in other locations in the heating system where regulation is required.
RA-N valve pre-setting values can be easily and accurately adjusted without tools (manufacturer's setting = N):
- Remove the protective cap or thermostatic head.
- Locate the reference mark.
- Lift and turn the set ring until the required initial setting value aligns with the reference mark.
- The initial setting can be selected in steps from 1 to 7. The setting value N means that the valve is fully open. This setting can be used as a flushing position when dirt needs to be flushed out of the system. In one-pipe systems, the N setting must be used.
- When the RA-N thermostatic valve with pre-setting is installed on the supply pipe to the radiator, there is no need to install a return flow valve on the return pipe (e.g., RLV-S or similar).
