Differential pressure controllers

AFP 2 / VFG 22(1)

The controller is a self-acting differential pressure controller primarily for use in district heating systems. Direct operated, reliable and high precise controller closes on rising differential pressure.The controller has a control valve, an actuator with one control diaphragm and spring for differential pressure setting.Further on two valve versions are available:∙ VFG 22 with metallic sealing cone∙ VFG 221 with soft sealing coneTogether with Danfoss intelligent electrical actuator AMEi 6 intelligent optimization functions are available:∙ iNET-intelligent network balancing

AVP (PN 25)

AVP(-F) is a self-acting differential pressure controller primarily for use in district heating systems. The controller closes on rising differential pressure. The controller has a control valve, an actuator with one control diaphragm and handle for differential pressure setting (fixed setting version (available on special request) is without handle).

AVP/ AVP-F (PN 16)

AVP(-F) is a self-acting differential pressure controller primarily for use in district heating systems. The controller closes on rising differential pressure. The controller has a control valve, an actuator with one control diaphragm and handle for differential pressure setting (fixed setting version (available on special request) is without handle).

AVPL

AVPL(-F) is a self-acting differential pressure controller primarily for use in district heating systems. The controller closes on rising differential pressure. The controller has a control valve and an actuator with one control diaphragm. It can be used on primary side of house substations for smaller systems such as one and two-family houses. The controller could be used to control the differential pressure across radiator systems and similar systems to keep a constant differential pressure even with a variable system resistance kva and/or supply pressure Δp0.
