with 60° cone for connection of the
burner hoses.
The product features two separate
float chambers. The lower float
chamber contains the operating float;
the upper float chamber contains the
safety float. The upper float chamber
keeps oil foam from escaping via the
vent opening (for example, during
commissioning/filter replacement)
and indicates malfunctions of the
vent valve.
Flow-Control 3/K HT differs from
Flow-Control 3/K by a non-transpar-
ent, plastic float chamber and FKM
seals. The product Flow-Control 3/
K HT is suitable for applications with
vegetable oil or substances with
higher temperatures.
