VDHT 3/2 way zone drain valves

The 3/2-way valves are designed for applications in high-pressure humidification and adiabatic cooling systems.Each valve has an IN, OUT and DRAIN port. When the valve is not in operation the connec-tion between IN and OUT is closed while the connection between OUT and DRAIN stays open. This allows to instantanously relief the pressure at shut down from the application, typically a nozzle branch, to prevent the nozzle from dripping. If desired, the nozzle branch can be entirely drained after shut down to avoid bacterial growth. Furthermore, each valve has its individual properties to match exactly the specific needs in size and functionality.

All of our valves are made of stainless steel (AISI 304) and are suitable for potable and technical water. They have an extremely long service life for at least one million operations and are even then very easy to service. Inline valves are available with European BSP thread (G-thread) and American National Pipe Thread (NPT). For the VDHT 15EC Danfoss offers a wide range of single and multiple manifolds.

The enclosure rating is IP67, including any standard coil. A large variety of coils for various supply voltages is available for all our valves.

If the recommendations in the manual are not followed, Danfoss reserves the right to void the warranty.
