Application

RLV Straight RLV Angle 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.

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).

The lockshield valve, type RLV, is available in
an angle version as well as a straight version.
Finish: plain brass or nickel plated.

System

The RLV lockshield valves can be preset to
limit the max. water flow within the following
setting area:

RLV 10: k
RLV 15: kv = 2.5 m3/h
RLV 20: k

= 1.8 m3/h

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.
