What it is

The Danfoss 065Z0421 is a rotary three-way valve with a DN40 body, a Kvs value of 25 and Rp1 1/2 connections. It is used to divert or mix flow between ports in heating and hot water circuits. The rotary design provides a compact body with a quarter-turn operating action.

Before you order

  • Confirm the mating pipework is Rp1 1/2 and that DN40 matches the line size on site.
  • Check the required Kvs of 25 against the design flow and pressure drop for the circuit.
  • Compare against the markings on the existing valve to confirm the part number and configuration before ordering.
  • Confirm the port arrangement and how the valve is to be operated in your application.
