Direct operated hydraulic servo valves

A directional control and servo valve comprising:

• a valve housing having a space, and a plurality of first cavities, wherein each first cavity of the plurality of first cavities incorporates a port for enabling liquid flow in the valve housing;
• a valving element having two sides thereof, each side having a plurality of second cavities that corresponds to the plurality of first cavities, the plurality of second cavities on each side are symmetrical to each other;
• the valving element comprising a plurality of webs formed in the plurality of webs formed in the plurality of second cavities, each web of the plurality of webs separates the plurality of second cavities on each side from each other, the plurality of webs having a plurality of holes configured to connect the plurality of second cavities of the two sides;
• wherein the valving element is disposed in the space of the valve housing such that an assembly formed therebetween configures a plurality of control edges that separates at least one first cavity of the plurality of first cavities with respective at least one second cavity of the plurality of second cavities to form control orifices that are symmetrical along the two sides of the valving element, wherein the valving element is rotated along an axial direction thereof to uncover the control orifices to allow the liquid flow to pass therealong to divide the liquid flow in symmetrical pattern along the valving element, and wherein the liquid flow is also enabled along the two sides of the valving element through the plurality of holes.
