AVPB/AVPB-F Differential Pressure Controller
Brand: Danfoss
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 maximum 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).
