Sundstrand Sauer Danfoss Hydraulic Series 40 M46 Charge Check Spring Change
Sundstrand Sauer Danfoss Series 40 M46 Charge Check Valve
The charge check valve has been improved by elevating the spring force on the check valve spring used in the charge check valve. It will help by making sure the check valve is closing under cold system operations. The new replacement spring is interchangeable with the older version. But the older spring style will no longer be available as a service part.
