Data Sheet
Lockshield Valve Type RLV - with Facility for Connection to Drain Tap
Application
RLV straight |
RLV angle |
Drain tap |
By means of a RLV lockshield valve every radiator can be shut off individually to allow trouble-free maintenance or repair without affecting other radiators in the system.
RLV lockshield valves are available in angle versions as well as straight versions. Finish: Nickel plated.
RLV lockshield valves can be preset to limit the max. water flow within the following setting area:
RLV 10: |
kvs = 1.8 m³/h |
RLV 15: |
kvs = 2.5 m³/h |
RLV 20: |
kvs = 3.0 m³/h |
Factory setting is fully open valve. Dimensions correspond to DIN 3842-1.
Accessories for RLV:
▪a drain tap for draining or filling of the radiator
▪a brass handwheel, used when radiators with RLV lockshield valves are removed.
In order to avoid deposition and corrosion the composition of the hot system water must be in accordance to the VDI 2035 guide line (Verein Deutscher Ingenieure).

RLV |
|
The RLV lockshield valve is intended for |
|
mounting on the outlet of the radiator. |
|
To enable subsequent draining of the radiator |
|
water, the lockshield valve should be mounted |
|
with its cover towards the front. |
|
Drain tap |
|
For mounting and operation of the drain tap, the |
|
following procedure is recommended: |
Setting |
Setting of max. water flow: |
|
▪ Close the valve by means of a 6 mm Allen |
|
key. |
|
▪ Regulate the water flow by opening the |
|
valve. The capacity diagrammes on page 3 |
|
show the water flow at 1/4 - 4 turns and for |
|
fully open valve (kvs). |
1.Shut off the radiator inlet valve. As a safety precaution the thermostatic sensor should be replaced by a Danfoss manual shut off handle, code no. 013G3300.
2.Remove the cover and shut off the valve by means of a 6 mm Allen key.
3.Mount the drain tap and align the drain branch, which can revolve in any direction.
4.Open the valve for draining.
