four-column hydraulic pressIs there a transition position for the two-position directional control valve?
Yes!The two-position directional control valve has only two positions, but the two-position directional valve also has an intermediate transition position. When moving from one position to another, the intermediate position passed is called the transition position. That is, when the valve core switches from one end position to another, the actuator feels the function within a fraction of a second. H-type and O-type are common transition position functions. In the spool reversing process, the O-type transition position function can prevent the hydraulic pump output pressure drop.
If the user has a request for the transition state during the transposition, it must be specified when ordering. On the graphic symbol is to use the dotted line to indicate the transition position function. As shown in the figure
