ABSTRACT:
A valve arrangement is illustrated and described, in particular an electronic expansion valve arrangement, for pneumatic or hydraulic pressure media comprising a valve housing having a first medium connection and a second pressure medium connection, which are connected together by a throughflow space formed in a cavity of the housing, and a slider element which is arranged in the valve housing and cooperates with a valve seat, with the slider element being operationally connected to a positioning element of a drive and being displaceably guided parallel to the valve seat between a closed position, in which the one contact surface of the slider element closes a throughflow opening formed by the valve seat, and an open position, in which a throughflow passage formed in the slider element frees the throughflow opening. The valve arrangement can be installed in a simple manner in that the slider element is arranged in a frame which is connected to or held on the positioning element and is tiltable relative to the frame about at least two axes and displaceable transversely to the contact surface.
