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.
Intelektualioji elektros pavara AMEi 6 iSET
AMEi 6 iSET pavara skirta centralizuoto šildymo / aušinimo šilumos punktų veikimui intelektualiai optimizuoti. Įgalina automatiškai reguliuoti Δp nustatymą AFP 2, AFPB 2, AFPQ 2 ir AFQMP 2 reguliatoriuose, naudojamuose centralizuoto šildymo / aušinimo sistemose.
Tai – sprendimas, skirtas dinaminės centralizuoto šildymo sistemoms su plačia minimalaus – maksimalaus srauto aprėptimi (karšto vandens buitinėms reikmėms tiekimas) ir sistemoms, kuriose naudojama netinkamo pajėgumo reguliavimo įranga (per dideli reguliavimo vožtuvai, netinkamai parinkti vožtuvai / charakteristikos, prastas reguliavimo koeficientas...).
Automatinio stabilizavimo funkcija stebi valdymo signalą ir stabilizuoja svyravimus esant dalinės / mažos apkrovos darbo sąlygoms, sureguliuodama Δp virš reguliuojančio vožtuvo su pavara (MCV).
Nuolat tobulinamas MCV eksploatavimas realiuoju laiku leidžia užtikrinti stabilesnį reguliavimą be svyravimų ir srautą, atitinkantį realius poreikius (pertekliaus prevencija).
Dėl to antriniame kontūre užtikrinamos pastovios temperatūrinės sąlygos, pagerėja ΔT pirminėje pusėje ir pailgėja sumontuotos įrangos tarnavimo laikas.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.
