Drain tap |
By means of a lockshield valve, type RLV, every radiator can be shut off individually to allow trouble-free maintenance or repair without affecting other radiators in the system.
The lockshield valve, type RLV, is available in an angle version as well as a straight version. Finish: plain brass or nickel plated.
The RLV lockshield valves can be preset to limit the max. water flow within the following setting area:
RLV 10: |
k |
v |
= 1.8 m3/h |
|
RLV 15: |
k = 2.5 m3/h |
|||
RLV 20: |
k |
v |
= 3.0 m3/h |
|
v |
||||
|
|
|
||
Factory setting is fully open valve. Dimensions correspond to DIN 3842-1.
Accessories for RLV:
-a drain tap for draining or filling the water in the raditator,
-a brass handwheel: a tool which is used when radiators with RLV lockshield valves are removed.
In order to avoid deposition and corrosion the composition of the hot water must be in accordance with the VDI 2035 guideline (Verein Deutscher Ingenieure).
