WebThe Root Cause of Hydraulic Cylinder Drift. A popular misconception involving hydraulic cylinders is that if the piston seal is leaking, the cylinder will drift. While a leaking piston seal can be the root cause of cylinder drift, the physics involved are often misunderstood. Filtration rates of 2 microns or less are possible, due to the pressure available … WebThe following can cause the cylinders to drift up: Wrong Directional Valve Installed. Sometimes the float center directional valve gets replaced with a closed center valve. When this happens, the directional valve will close first blocking the flow to the cylinder when it is de-energized. This will cause the check valves to stay open momentarily.

WebApr 19, 2016 · Source/Symptom: Drift Piston seal leaks can cause a cylinder to drift from its normal position. To check the seal, pressurize one side of the piston and observe leakage from the opposite side. Virtually no air should leak past pistons equipped with soft seals. Replace seals as needed. Other circuit leaks also can cause a cylinder to drift.
