Manufacturer documents are provided in their original language; the language may vary by file. Series-level ratings are a guide: check the exact model and operating conditions in its data sheet.
Eaton pilot-to-close check valves
A pilot-to-close valve uses pilot pressure to close the check element, whereas a pilot-to-open valve uses it to open the element. Referenced models include Eaton 5CK30, 5CK120 and 5CK300. For pilot-to-open designs, return to the pilot-operated check valve documentation section.
