Data Sheet

Lockshield Valve Type RLV - with Facility for
Connection to Drain Tap

Application

RLV straight RLV angle Drain tap

Principle

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).

Setting

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 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.
