Data sheet ESBE Type F
3 & 4-Way Rotary Valves
VDKIN322 © Danfoss 02/18
3-Way Valves
• Ideal valves for mixing and diverting
applications
• Reduces risk of low temperature water
returning to boiler
4-Way Valves
• Double mixing function, providing
proportional mixing from source to
system and system to source
• Reduces risk of low temperature water
returning to boiler.
