         Swing tip check vanalar en yayg\u0131n kullan\u0131lan check vana tipidir. Swing tip check vanalar\u0131n \u00e7al\u0131\u015fan par\u00e7as\u0131 mente\u015feli bir disktir. Mente\u015fe pimi \u00fczerinde rahat\u00e7a hareket edebilir. Ak\u0131\u015fkan bir y\u00f6nde akarken disk ak\u0131\u015fkan\u0131n akmas\u0131na izin verir ama ters y\u00f6nde ak\u0131\u015f ger\u00e7ekle\u015fti\u011finde ise disk ge\u00e7i\u015fi kapar ve ak\u0131\u015fkan\u0131n ge\u00e7i\u015fi engellenmi\u015f olur yani ak\u0131\u015f tek y\u00f6nl\u00fc olur.<\/p>\n

    Swing tip check vanalarda diskin yava\u015f kapat\u0131lmas\u0131 gerekir. Aniden kapanmas\u0131 bas\u0131n\u00e7 dalgalanmas\u0131na neden olur. Bas\u0131n\u00e7 dalgas\u0131 titre\u015fim ve g\u00fcr\u00fclt\u00fc olu\u015fturaca\u011f\u0131ndan borunun \u00e7atlamas\u0131 gibi ciddi sorunlar\u0131 ortaya \u00e7\u0131kar\u0131r.<\/p>\n

        Ball check vanalar\u0131n \u00e7al\u0131\u015fan par\u00e7as\u0131 bilyad\u0131r. Swing tip check vana ile ayn\u0131 \u00e7al\u0131\u015fma prensibine sahiptir. Hareketli olan mente\u015fe yerine bilya ak\u0131\u015f\u0131 keser ya da a\u00e7ar.<\/p>\n

         \u00c7ift klapeli check vanalar su ak\u0131\u015f\u0131 ile a\u00e7\u0131l\u0131r. Ak\u0131\u015f olmad\u0131\u011f\u0131 durumda, su darbesi ters ak\u0131\u015f\u0131 meydana gelmeden yay mekanizmas\u0131 ile otomatik olarak kapan\u0131r. \u00c7ift klapeli \u00e7ek vanalar\u0131n kullan\u0131m\u0131 pompa \u00e7al\u0131\u015fma ve durma gibi durumlarda su darbelerini \u00f6nler. \u00c7ift klapeli \u00e7ek vanalar az yer kaplamas\u0131 ve dikey montaj olana\u011f\u0131 ile \u00e7alpara \u00e7ek vanalara g\u00f6re avantaj sa\u011flar. Genellikle pompa \u00e7\u0131k\u0131\u015f\u0131nda ve su darbesi olabilecek yerlerde kullan\u0131l\u0131r.<\/p>\n
