Directional valves are used to control water ow direction.
The directional valves are pilot operated On/O 2/2-way seat valves electrically activated by 1 coil.
Corrosion resistant surfaces
Easy to clean surfaces
The seat valve design ensures zero leakage
The valve housing comes in standard version in stainless steel AISI 304 (W. nr. 1.4301). The valve is available as a normally closed valve (NC) or as a normally open valve (NO).
The water supplied to the valve must be ltered: 10 µm absolute, β recommended.

Temperature
Operation on (clean) water:
Fluid temperature and ambient temperature: 3 °C – 50 °C.
Operation on water containing antifreexe:
Fluid temperature and ambient temperature:

1).
Storage temperature:
-40 °C – 70 °C provided that the valve is drained of uid and stored "plugged".
Antifreeze protection
1)
If a system requires antifreeze protection, Danfoss recommends Dowcall N or Chillsafe mono propyl­ene glycol from the Dow Chemical Company and Arco Chemical Company, respectively. Both antifreezes are biologically degradable and must be used together with demineralized water. Mixing ratio must be:
• Min. 30% antifreeze and 70% demineralize water providing frost protection to -13 °C and preventing biolm in the system.
• Max. 50% antifreeze and 50% demineralize water due to increased viscosity, providin frost protection to -30 °C.

Inline valves are mounted in line in ow direction (follow the arrow on the valve) and xed either
The valve is designed to be mounted on a block with CETOP 3-port connection. Four stainless steel screws and four O-rings are supplied with the valve for mounting. Remember to smear/
directly in the pipe connections or with bolts in the xation holes on the valve.
spray the threads on the screws with Molykote® D pasta from Dow Corning, or Klüber UH1 84-201 from Klüber lubrication, before mounting the valve.
Coil on valves with short armature tubes (NC and NO valves)
1. Place the o-ring on the armature tube.
2. The coil is clicked on by means of a light pressure by hand – without using tools.
