Check Valves, Systems and Methods of Operation of Same |
| 摘要 |
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. |

1. System for the actuation of the sealing element of a check valve comprising a controller configured so that said sealing element is forced in a non-sealing position corresponding to an opening degree of the valve equal to or higher than a first predefined opening degree when the increase of the opening degree with respect to the sealing position of said sealing element is equal to or greater than a predefined threshold. |
