Vana bilyeleri, vana sistemlerinde kritik bile\u015fenlerdir.

Bir\u00e7ok vana tertibat\u0131nda bilye, vana yata\u011f\u0131yla do\u011frudan temas eder, bu nedenle yuvarlakl\u0131k, y\u00fczey kalitesi, malzeme sertli\u011fi, korozyon direnci ve boyutsal tutarl\u0131l\u0131k; s\u0131z\u0131nt\u0131 oran\u0131n\u0131, servis \u00f6mr\u00fcn\u00fc ve g\u00fcvenilirli\u011fi do\u011frudan etkiler.<\/p>\n\n\n\n
