1 piece of (DF1 50F) or 2 pieces (DF250F) of
hydraulic output multiple unit valve with slide valve
type may be optional. Two pieces of valve plate are
controlled by C/D control handle respectively to
control two double-acting cylinders on the control
implements. Fix the multiple unit valve assembly on
the fixing board (which is connected with half-axle
housing of the rear axle) of the multiple unit valveby
4 bolts(M10),the inlet/return opening connects with
the gear pump/lifter respectively, and the outlet
connects with the inlet of the distributor.
Each piece of control valve is with 2 quick joints

shown if Figure 2-58, use the sealing cover to seal it when it is not used. spare male connector is connected
with female connector of quick change coupler, and then connected with oil inlet and outlet of oil tank on the
farm machine Control handle "A” controls 1St circuit hydraulic output AB2 while control handle “B" controls
2nd hydraulic output AB1. if connecting with single-acting cylinder, oil pipe of the cylinder shall connect with
outlet A1 of the first pipe or outlet A2 0f the second pipe. Move up/down the control handle “C"/”D", the
single-acting or double-acting oil cylinder will finish the corresponding action. Two hydraulic output valves
can screw in or screw out single/double-action exchange screw ”E” on the multi-way valve to achieve
single-action hydraulic output or double-action hydraulic output. See diagram 2-60 Unscrew and exit bolt E
counter clockwise, single-function hydraulic output can be perform. On the contrary, the screw “E" is fully
screwed in to achieve double-action hydraulic output.
