Data sheet Lockshield valve type RLV
with facility for connection to drain tap
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.
