Control valves with superior protection for any need
Outdoor refrigeration installations usually come with significant maintenance costs. This is mainly down to corrosion issues, as components are exposed to harsh weather and general hazards day and night.
With Danfoss, you get a large range of innovative, intuitive control valves with superior protection. Pick between our TLP-treated components with an extra layer of protection compared to market alternatives – and our stainless-steel options with minimum corrosion and minimum maintenance costs.
Today, more than 50% of new builds utilize stainless steel piping, effectively making it the industry standard. That’s one reason we have made more than 80% of Danfoss valves available in stainless steel, providing a durable, high-performance option for new installations.

This multi-ported Danfoss control solution offers you significant savings by substituting a string of valves with just one valve station. 80% of the products are stainless steel, the rest is TLP coated for reduced maintenance and replacements.

Danfoss ICV Flexline™ gives you one platform for multiple control solutions. The modular concept offers outstanding flexibility with a large range of products based on one common valve body. With Danfoss ICV Flexline™, you get TLP-coated solutions that enhances reliability, safety, and sustainability, now and in the long run.
