  • Publication number: 20140311586
    Abstract: A control valve for hydraulic media is provided. The control valve includes a valve body having four ports. A first seat, a second seat, and a dual seat are positioned in the valve body between the ports. Two poppets, each including a disc and a cup, with a spring located therebetween, are arranged on a cylindrical pin with an enlarged engagement portion that is slidably supported within the valve body. A solenoid assembly movable in an axial direction within the valve body contacts the cylindrical pin and adjusts the position of the discs and cups of the poppets with respect to the seats of the valve body to minimize unwanted leakage between the ports.
