Definitions
- the invention consists essentially in the fact that the valve closure member is designed as a valve ball and can be pressed against a conical valve seat.
- Such a design ensures on the one hand that a tight closure of the valve is guaranteed even if the valve closing member or the valve seat are slightly damaged by the impurities present in heavy oil, and on the other hand, that at an inadmissibly high wear of the valve closure member replacement in the same simple way is possible.
- the embodiment of the invention is to be described as particularly resistant to wear and it may in the event of wear or malfunction occurring the valve ball and, if necessary, the valve seat-bearing intermediate plate are exchanged in a simple manner without affecting other parts of the control valve.
