text: Additionally, the use of washers 38 abutting the end of the spool shafts 16 and 17 prevents the fluid pressure in the valve chamber ends 13 and 14 from acting on the entire outer face of the shafts, thereby effectively minimizing the force developed by the pressure differential existing between the chambers 13 and 14 and thereby further facilitating rapid neutral positioning of the spool upon de-energization of the operating solenoid coil.
