Danfoss often has 3 versions of a spare parts kit for our valves, although not for every kind. The three types are:
Inspection Kits, which include gaskets and o-rings
Repair Kits, which include all parts found in the inspection kit, plus the packing gland (not available for a check valve and strainer)
Overhaul Kits, which include all parts in the repair kit, plus any parts that could be damaged or worn due to normal use
Our Industrial Refrigeration app can help you find the right spare part kit for your situation. Download it here.
