Frequently Asked Questions
Q: What is the MO 12E123 damping valve seat?
A: The MO 12E123 is a damping valve seat component for Mobile ECO I-55 manual pallet jacks. It forms the sealing surface where the damping valve spindle seats, controlling hydraulic flow during load lowering.
Q: Which Mobile pallet jack models use the MO 12E123?
A: The MO 12E123 is compatible with Mobile ECO I-55 manual pallet jacks. Alternate model designations include ECO I55 and ECO I 55.
Q: What is the function of the MO 12E123 in the damping system?
A: The MO 12E123 serves as the sealing surface in the damping valve assembly. When the valve spindle (MO 12E122) seats against it, the combined action with the compression spring (MO 12E121) controls the rate at which hydraulic fluid flows during load descent.
Q: How do you know if the MO 12E123 needs replacement?
A: If the damping valve leaks hydraulic fluid when seated, or if the pallet jack exhibits uncontrolled lowering despite replacing the spindle, the valve seat may be pitted, scored, or damaged. Inspect for surface irregularities at the sealing surface.
Q: Are the MO 12E123, MO 12E122, and MO 12E121 typically replaced together?
A: When disassembling a damping valve assembly, it is good practice to replace all three components as a unit. The spindle and spring work against the seat, and wear on one component can accelerate wear on the others. Replacing all three ensures proper function and extends service life.
