Differenstryksregulator og flowregulatorer/-begrænsere
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)
AVPQ 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 (fixed setting version (available on special request) is without handle).

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.
Intelligent electrical actuator 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.Intelligent elektrisk motor AMEi 6 iSET
AMEi 6 iSET -motor til intelligent optimering af fjernvarme-/køleunderstationens drift. Automatisk justering af Δp-indstillingen på AFP 2-, AFPB 2-, AFPQ 2- og AFQMP 2-regulatorer, der anvendes i fjernvarme-/kølesystemer.
Løsning til dynamiske fjernvarmesystemer med et bredt interval for min.-maks. flow (varmt brugsvandsforsyning) og til systemer med forkert dimensioneret reguleringsudstyr (overdimensionerede reguleringsventiler, forkert ventilvalg/-karakteristik, dårligt reguleringsforhold ...)
Autostabiliseringsfunktionen overvåger styresignalet og stabiliserer pendlinger under driftsforhold med delvis/lav belastning ved at justere Δp over motorventilen (MCV).
Konstant forbedring af MCV-driften i realtid giver mere stabil styring uden pendlinger og flow, der leveres op til de reelle behov (forebyggelse af overflow).
Dette resulterer i stabile temperaturforhold på sekundærsiden, forbedring af ΔT på primærsiden og længere levetid for installeret udstyr.
