Internal shock absorber valve plate of piston assembly

Use locationIt is installed inside the shock absorber piston assembly, located in the piston valve system or bottom valve system, and works in conjunction with the valve seat, spring, and orifice.

FunctionIt opens or closes with the flow of oil during the compression and recovery strokes, adjusting the flow rate of the orifice to generate the required damping force. By stacking valve plates with different thicknesses, diameters and combinations, the damping characteristics can be precisely adjusted.

Materials and craftsmanship
