Design and principle of operation

3.1 Versions

Type 46-5 and Type 46-6 Differential Pres-
sure Limiters with Flow Limitation are de-
signed for installation in the return flow pipe,
e.g. a district heating station with indirect
connection.
− Type 46-5 · With fixed differential pres-
sure limit and adjustable flow rate · With
internal overload protection (excess pres-
sure limiter) in the actuator
− Type 46-6 · With adjustable differential
pressure and flow limitation · With inter-
nal overload protection (excess pressure
limiter) in the actuator

3.3 Technical data

3.3.1 Process medium and
scope of application
Differential pressure and flow rate limitation
for district heating systems with indirect con-
nection, extended piping systems and indus-
trial applications · DN 15 to 50 · PN 16/25
Suitable for liquids
es up to 80 °C
The valve closes when the differential pres-
sure rises. The flow rate is limited.
_
The materials used in the regulator are also
1)
resistant to high concentrations of glycol. Nev-
ertheless, glycol reacts when it comes into
contact with metals and causes acids to form.
We cannot prevent this reaction. Therefore,
prevent it by using suitable inhibitors.
