Area of use

Manifold FLK facilitates installations where the connection pipes location varies.
The radiator can be fold out for cleaning.
The radiator manifold is regulated with a thermostatic head, thermal actuator or handwheel.


The thermostatic radiator valve offers precise pre-setting functionality concealed under the stuffing
box; pre-setting is carried out with the FN2 pre-setting key by opening a number of turns from closed valve in line with the pressure drop diagram.
Setting is made easier using the FV9 pre-setting tool.
The valve is supplied with a grey protective cap to indicate pre-setting. The protective cap can be used to close the radiator during the construction stage. When balancing, a nominal opening of 2°K should be set by first screwing the protective cap all the way to the bottom and then opening it three quarters of a turn.
The diverter has built-in shut-off. FLK 10 fi ts single radiators without convector plates and FLK 20 fits single radiators with convector plates and double panel.
FLK is connected with plastic or Alupex pipes dimension 16.
