AFPB/AFPB-F Differential Pressure Controller for VFQ 2 (1)
Brand: Danfoss
The controller 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 spring for differential pressure setting.
Further on two valve versions are available:
- VFQ 2 with metallic sealing cone
- VFQ 21 with soft sealing cone (on special request)
