Diverting valve
VZC, VZD
- Fast change-over.
- Anti-jamming program every 7th day.
- 0-percentage leakage.
- Auxiliary switch available.
Series VZC, VZD is a range of compact diverting valves in brass for use in heat pumps, underfloor heating or HVAC applications. The main feature is the ability to rapidly change the flow direction between two circuits meaning a energy-effecient operation. The actuator series VZC has an Molex-type connector for quick cable connection to the control unit. The actuator series VZD is delivered with a fixed cable and has an enclosure rating of IP40. As an option series VZC, VZD is available with auxiliary switch.
