Hydraulic system with a dynamic seal

A system, comprising:

• a first valve device and a second valve device, each of the first valve device and the second valve device including:
• a valve body and a valve element slidably disposed within a passageway formed in the valve body, wherein a first segment of the valve element and the valve body are arranged to define a working chamber to receive fluid at a first pressure, and the valve body and the valve element are arranged to define a control chamber to receive fluid at a second pressure, the valve element having a first land and a second land axially spaced from one another, the valve element including a retainer proximal to the first and second lands, wherein a spring is disposed around the retainer;
• a check stem disposed about a portion of the first land of the valve element, the check stem having an enlarged portion extending radially beyond the second land into the working chamber to selectively interface with a portion of a body inner surface of the valve body;
• a sleeve disposed about a portion of the second land of the valve element, the sleeve fixedly engaged to the body inner surface of the valve body, wherein an outer diameter of the sleeve is greater than an outer diameter of the check stem;
• an annular seal element disposed about the second land between the second land and a sleeve inner surface of the sleeve, wherein the annular seal element and the second land together are arranged to separate the working chamber and the control chamber and to move with axial movement of the valve element relative to the sleeve;
• an axial passage formed within the valve element spaced from the check stem;
• and
• a first radial passage, a second radial passage and a third radial passage formed within the valve element spaced from the check stem, each of the first radial passage, the second radial passage and the third radial passage extending radially from the axial passage;
• a pressure compensating valve coupled to the working chamber of the first valve device and the working chamber of the second valve device via a supply fluid passage;
• and
• a shuttle valve fluidly coupled to the pressure compensating valve, wherein one of the first radial passage, the second radial passage, and the third radial passage of the first valve device is fluidly coupled to shuttle valve, and one of the first radial passage, the second radial passage, and the third radial passage of the second valve device is fluidly coupled to shuttle valve.
