Chiwongolero chachangu cha ntchito ya PVC Buku la valavu yoyitanitsa kawiri

Valavu yapamanja yapawiri-action ndi chida chodziwika bwino cholumikizira mapaipi apanyumba m'moyo wathu.Kodi mumavutika osadziwa momwe mungagwiritsire ntchito?Ichi ndi chiwongolero cha ntchito ya PVC manual double-order mpira valve yolembedwa kupyolera muzochita.

Ndikukhulupirira kuti kudzera mu opareshoni iyi, muthanso mosavuta komanso mwachangu luso logwiritsa ntchito buku la PVC pawiri.
