Quick guide from the manual

This document provides essential instructions for maintaining the anti-corrosion treatment applied to Danfoss ICS, ICM, and ICLX valves. The primary requirement is to ensure the valve is disassembled only immediately before the welding or brazing process to prevent corrosion.

Anti-Corrosion Treatment Overview

The internal surfaces and weld connections of these valves are treated with an anti-corrosion agent. To maintain the effectiveness of this treatment, follow the handling guidelines provided below.

Handling and Storage Procedures

If the valve is not being installed immediately, or if the function modules are to be left disassembled for any length of time, you must take steps to protect the surfaces:

  • Disassembly: Only disassemble the valve just prior to the welding or brazing process.
  • Protection: If modules are left disassembled for an extended period, protect them using one of the following methods:
    • Place the function modules in a polyethylene bag.
    • Apply a rust protection agent, such as refrigeration oil or BRANOROL, to the surfaces.

Practical help

Common problems

Corrosion on internal surfaces

Ensure the valve is disassembled only immediately before welding/brazing and protect disassembled modules with oil or a bag.

Long-term storage of disassembled modules

Apply rust protection agent (refrigeration oil or BRANOROL) or store in a sealed polyethylene bag.

Before use

  • Verify the valve type (ICS, ICM, or ICLX).
  • Prepare the welding/brazing area.
  • Have rust protection agent (refrigeration oil or BRANOROL) ready if storage is required.
  • Have polyethylene bags ready if storage is required.
