Data sheet
Differential pressure controller with flow limitation and
with integrated control valve (PN 16)
AHPBM-F – flow mounting, fixed setting
Description
AHPBM-F is a self-acting differential pressure
controller with flow limitation primarily for use in
direct-connected district heating systems with
mixing loop only. The controller closes on rising
differential pressure or when set max. flow is
exceeded.
It can be combined with Danfoss electrical
actuators AMV(E) and controlled by ECL
electronic controllers.
The controller has a control valve with adjustable
flow restrictor, connection neck for electrical
actuator, and an actuator with one control
diaphragm.
Controllers are used together with Danfoss
electrical actuators:
- AMV(E) 10
- AMV(E) 13 with spring return function
- AMV(E) 130, AMV(E) 140
- AMV(E) 130H, AMV(E) 140H with manual
override knob
AHPBM-F combined with AMV(E) 13 has been
approved according to DIN EN 14597.
Main data:
• DN 15-32
• kvs 1.0-6.3 m3/h
• PN 16
• Fixed ∆p setting:
- 0.12 bar for DN 15-20
- 0.14 bar for DN 25-32
• Temperature:
- Circulation water / glycolic water up to 30%:
2 … 120 °C
• Connections:
- Ext. thread (weld-on, thread and flange
tailpieces)
