Check Valves
Check valves are designed for installation in commercial refrigeration systems and civil or industrial air conditioning systems that use Group II fluids, as defined in Article 9, Section 2.2 of Directive 97/23/EC, meaning they are non-toxic, non-flammable, and non-explosive.
Check valves are also suitable for use with refrigerants listed and classified as L1 in Annex E of EN 378-1:2011, which belong to Group II. The special construction of these valves allows for their application in challenging temperature conditions, such as on the compressor discharge line.
