CHECK VALVES, SYSTEMS AND METHODS OF OPERATION OF SAME |
摘要 |
<p>A system and a method for actuating a sealing element (101) of a check valve (100) are shown wherein the sealing element (101) is forced to a non-sealing position corresponding to an opening degree of the valve (100) equal to or higher than a first predefined opening degree when the increase of the opening degree with respect to the sealing position (T) is equal to or higher than a predefined threshold. In this way, the problem of vibration or "chattering" of the sealing element of the valve is efficiently prevented.</p> |
