technical description
HeiMeieR Mikrotherm manual radiator valves made of corrosion-resistant gunmetal,
with white plastic hand wheel cap, tight-packed with protection film.
lengths according to din 3841 part 1. accurate presetting of the mass flow and finest heat
apportioning through a non-rising double spindle with a Mikrotherm presetting cone with
tandem sealing (metal and o-ring sealing). spindle for dn 10 to dn 25 with double o-ring
sealing. spindle sealing for dn 32 through stuffing box packaging which can be tightened.
Can be retrofitted as a thermostatic valve by replacing the Mikrotherm insert with a
thermostatic insert. Can be connected to a threaded pipe, or with compression fittings to a
copper, precision steel or multi-layer pipe. For HeiMeieR Mikrotherm, only use the auxiliary,
labelled HeiMeieR compression fittings (label e. g. 15 tHe).
Permitted operating temperature tB 120°C (248°F). Permitted operating pressure
PB 10 bar, low pressure steam 110°C (230°F)/ 0.5 bar.

Application
the HeiMeieR Mikrotherm manual radiator valve is used in warm water pump heating systems, gravity or low pressure steam
systems. With models in angle and straight form from dn 10 to dn 32, the manual radiator valve can be used for a number
of different purposes. the non-rising double spindle with the Mikrotherm presetting cone makes hydraulic balancing through
presetting possible. the aim here is to provide e. g. all heat consumers with hot water according to their needs.
