Data sheet
Lockshield valve type RLV-S - for individual shut-off
Application
RLV-S Straight
RLV-S Angle
By means of a lockshield valve, type RLV-S, every radiator can be shut off individually to allow trouble-free maintenance or repair without affecting other radiators in the system.
Accessory for RLV-S: - Brass handwheel: a tool which replaces the thermostat when radiators with RLV-S lockshield valves are removed.
The lockshield valve, type RLV-S, is available in an angle version as well as a straight version. Finish: plain brass or nickel plated.
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 RLV-S lockshield valves can be preset to limit the max. water flow within the following setting area: RLV-S 10: kvs = 1.5 m3/h RLV-S 15/20: kvs = 2.2 m3/h
System
Factory setting is fully open valve. Dimensions correspond to DIN 3842-1.
RLV-S
RLV-S is intended for mounting on the outlet of the radiator.

Setting of max. water flow: - Close the valve by means of an Allen key: DN 10 = 6 mm; DN 15/20 = 8 mm. - Regulate the water flow by opening the valve. The capacity diagrammes on the opposite page show the water flow at ¼ - 4 turns and for fully open valve (kvs).
