Valavu yowunikira yachitsulo yoponyedwa ndi chitsulo chogwedezeka

Mavavu oyesera a rabara opangidwa ndi chitsulo chozungulira ndi osavuta kupanga koma olimba kugwiritsa ntchito pazinthu zosiyanasiyana.

Ndi zigawo zitatu zazikulu zokha: thupi, chotchingira ndi chivundikiro, pali ntchito yokonza pang'ono. Komabe, chotchingiracho chikhoza kusinthidwa mumphindi zochepa. Mpando wa valavu uli pa ngodya ya madigiri 45 pakati pa chitoliro, zomwe zimathandiza kuti madzi aziyenda molunjika kapena molunjika. Chotchingiracho chikatsegulidwa bwino, pali njira yolunjika yosatsekedwa, kotero zinthu zonse zakunja zimachotsedwa ndi pakati. Izi zimachotsa kutsekeka. Chifukwa cha njira yoyenda yosatsekedwa iyi, kutsika kwa kuthamanga kumakhala kochepa kwambiri kudzera mu cheke cha rabara chotchingira kuposa kudzera mu mavavu oyesera ozungulira.

Kawirikawiri ma valve a rabara otchingira ma swingcheck amapangidwa ndi chitsulo chosungunuka. Chotchingira ndi Buna-N koma chimatha kupangidwa kuchokera ku ma rabara osiyanasiyana opangidwa.
