Differenzdruckregler und Durchflussregler/-begrenzer
Product types shown: 18
AVPB, AVPB-F (PN 16)
AVPB (-F) is a self-acting differential pressure controller with flow limitation primarily for use in district heating systems. The controller closes on rising differential pressure or when set max. flow is exceeded.
The controller has a control valve with adjustable flow restrictor, an actuator with one control diaphragm and handle for differential pressure setting (fixed setting version is without handle).
AVPB, AVPB-F (PN 25)
AVPB (-F) is a self-acting differential pressure controller with flow limitation primarily for use in district heating systems. The controller closes on rising differential pressure or when set max. flow is exceeded.
The controller has a control valve with adjustable flow restrictor, an actuator with one control diaphragm and handle for differential pressure setting (fixed setting version is without handle).
AVPQ (PN16)
Der AVPQ ist ein selbsttätiger Volumenstromund Differenzdruckregler für den Einsatz überwiegend in Fernwärmesystemen. Der Regler schließt bei steigendem Differenzdruck bzw. wenn der eingestellte maximale Volumenstrom überschritten wird.
Der Regler besteht aus einem Regelventil mit einstellbarer Volumenstrombegrenzung, einem Antrieb mit zwei Stellmembranen und einem Handgriff für die Einstellung des Differenzdrucksollwerts.

– Außengewinde (Anschweiß-, Gewinde- und Flanschanschlüsse)
AVPQ, AVPQ 4 (PN 25)
AVPQ (4) is a self-acting differential pressure and flow controller primarily for use in district heating systems. The controller closes on rising differential pressure or when set max. flow is exceeded.
The controller has a control valve with adjustable flow restrictor, an actuator with two control diaphragms and handle for differential pressure setting.
AVQ (PN16)
AVQ ist ein selbsttätiger Volumenstromregler für den Einsatz überwiegend in Fernwärmeanlagen. Der Regler schließt, wenn der eingestellte maximale Volumenstrom überschritten wird.
Der Regler besteht aus einem Regelventil mit einstellbarer Volumenstrombegrenzung und einem Antrieb mit einer Stellmembrane.
Intelligenter elektrischer Stellantrieb AMEi 6 iNET
AMEi 6 iNET actuator for intelligent network balancing, enables remote adjustment of differential pressure (Δp) setting on AFA 2, AFD 2, AFP 2, AFPA 2, AFPB 2, AFPQ 2 and AFQMP 2 controllers, used in District Heating/Cooling systems.
Changing heat consumption requires changes in heat distribution. Therefore the Δp should be optimised at each branch. With iNET the Δp can be remotely adjusted. Input for pump optimization.Intelligenter elektrischer Stellantrieb AMEi 6 iSET
AMEi 6 iSET actuator for intelligent optimization of the District Heating/Cooling substation operation. Automatic adjustment of Δp setting on AFP 2, AFPB 2, AFPQ 2 and AFQMP 2 controllers, used in DHC systems.
Solution for dynamic DH systems with wide span of min - max flow (Domestic Hot Water service) and for systems with improperly sized control equipment (oversized control valves, wrong valve selection/characteristic, poor control ratio...).
Auto stabilization function monitors control signal and stabilizes oscillations at the partial/ low load operating conditions, by adjustment of the Δp over the motorized control valve (MCV).
Constant-real time MCV operation improvement led to more stable control without oscillations and flow delivered up to the real needs (overflow prevention).
This results in stable temperature conditions on the secondary side, improvement of ΔT on the primary side and longer lifetime of installed equipment.
