AFD Pressure Reduction Controller for VFG 2 (1) & VFGS 2

Brand: Danfoss

The controller is a self-acting pressure reduction controller primarily for use in district heating systems.

The controller is normally open and closes on rising differential pressure. 

The controller has a control valve, an actuator with one control diaphragm and a spring for pressure setting. 

Further on three valve versions are available: 
  • VFG 2 for water, with metallic sealing cone 
  • VFG 21 for water, with soft sealing cone
  • VFGS 2 for steam, with metallic sealing cone
