Controlador de pressão diferencial e controladores/limitadores de fluxo
Product types shown: 19
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. AMEi 6 iSET actuator for intelligent optimization of the District Heating/Cooling substation operation. Automatic adjustment of ∆p 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...)
