    320C Excavator Hydraulic System – Boom Drift Reduction Valve The boom drift reduction valve is placed in the boom circuit between the main control valve and the boom cylinders. When the joystick for the boom is in the NEUTRAL position, the boom drift reduction valve stops oil leakage from the head end of the boom cylinders.

  • How To Troubleshoot Hydraulic Cylinder Drift | Hydraulics

    A popular misconception about hydraulic cylinders is that if the piston seal is leaking, the cylinder will drift down. Fact is, if the piston seal is completely removed from a double-acting hydraulic cylinder, the cylinder is completely filled with oil and its ports are plugged, the cylinder will hold its load indefinitely - unless the rod-seal leaks.

  • Two Simple Solutions to Prevent Hydraulic Cylinder Drift

    Aug 27, 2015 · Hydraulic cylinder drift can be caused by an internal leak in the cylinder across the piston or an external leak. When internal leaks occur, the hydraulic fluid physically moves from one side of the piston to the other, creating an uneven distribution that causes the cylinder to move or "drift.". Leaks generally occur when the piston seals

    Option Anti Drift: Anti Drift is used in lifting functions when a specific position must be secured and guaranteed to be held for a longer period – for example, in the crane operation of an excavator. The Anti Drift function uses an additional valve to prevent the leakage that occurs in conventional control valves. This valve is located between

    (counterbalance valves) are absolutely necessary for the boom cylinders of an excavator. Excavators transport loads but they also perform work from a stationary position. When excavating, there should be no drift of the boom when the suspension is switched off. The operator must be able to use the excavator for accurate

  • Understanding hydraulics and cylinder drift | Heavy

    Sep 30, 2020 · Hydraulic drift is can result from internal leaks in piston seals, valves, or rod seals. These leaks can then create unequal pressure that causes the piston to move from its neutral position. You may not notice hydraulic drift at first, due to the drift being intermittent in nature. However, drift can increase over time and become more prominent.
