\u2013 La structure du tiroir \u00e9quilibr\u00e9 est adopt\u00e9e, la force axiale d\u00e9s\u00e9quilibr\u00e9e est faible, la diff\u00e9rence de pression admissible est grande et la stabilit\u00e9 est bonne.
\n\u2013 La grande surface de guidage du tiroir am\u00e9liore les oscillations caus\u00e9es par les courants de Foucault et les chocs et r\u00e9duit les dommages.
\n\u2013 Le bruit est r\u00e9duit d'environ 10 dB par rapport aux vannes de r\u00e9gulation ordinaires \u00e0 si\u00e8ge simple et double. La porte filaire a une structure simple et est facile \u00e0 assembler, d\u00e9monter et entretenir.
\n-Le corps min adopte un forgeage int\u00e9gral avec des performances fiables.
\n\u2013 Le corps de vanne est con\u00e7u selon le principe de la m\u00e9canique des fluides pour avoir une faible r\u00e9sistance d'\u00e9coulement de section \u00e9gale et une large plage de r\u00e9glage.<\/p>","protected":false},"excerpt":{"rendered":"
