| 摘要 |
The invention relates to a pressure control valve device for supplying corrosive media, in particular a corrosive fuel to an internal combustion engine, comprising a valve housing with a media inlet and a media outlet, a valve seat, which is fixedly provided in the valve housing (12) and has a valve opening that creates a connection between the media inlet and the media outlet, and a valve body, which is held such that it can be moved between a first end position and a second end position, wherein in the first end position it lies on the valve seat and closes the valve seat opening and in the second end position it at least partially exposes the valve seat opening, the valve body comprising a tubular housing. Also provided is a sealing element (100), which has a sealing lip (102), which lies against the housing (86) of the valve body (84) and interacts therewith in a sealing manner. At least the sealing lip (102) consists of a PTFE (polytetrafluoroethylene) material (Fig. 1). |
