H-piece valves, type RLV-KB, for valve radiators in

two-pipe systems.

Application

System

Ordering and Data

By means of the H-piece valve type RLV-KB,
every valve radiator with a centre distance
between the connections of 50 mm can be
blocked individually, e.g. in order to carry out
trouble-free maintenance without affecting
other parts of the system.

H-piece valve type RLV-KB is nickel plated
and is available in straight and angle
versions. Special adapters ensure that the
H-piece valve can be used both for radiators
with an internal thread of G ½ and with an
external thread of G ¾ . All adapters are self­sealing.

in accordance with the VDI 2035 guideline
