Ndikoyenera makamaka kuti mbale yagulugufe ya valavu yayikulu ikhazikike m'mimba mwake ya payipi.Mu gulugufe gulugufe thupi cylindrical channel, chimbale chimbale mozungulira axis kasinthasintha, kasinthasintha ngodya pakati 0 ° ~ 90 °, kuzungulira kwa 90 °, valavu ndi lotseguka kwathunthu.Mapangidwe ake ndi osavuta, otsika mtengo, osinthika osiyanasiyana ndi akulu.
Gulugufe chisindikizo cha valavu ndi mphira ngati mkhalapakati, ndi kutali ndi theka la mpira valavu, valavu ya mpira, chipata valavu zitsulo zolimba kusindikiza ntchito.Theka la mpira valavu pambuyo ntchito yaitali, mpando umatulutsanso kuda kuvala, adzapitiriza kugwiritsidwa ntchito, ndi kusintha tsinde ndi kulongedza ndondomeko kutsegula ndi kutseka valavu tsinde basi atembenuza 90 °, panali zizindikiro kutayikira, Kupanikizana kunyamula mabawuti a gland kachiwiri pang'ono, kulongedza kumatha kuzindikirika popanda kutayikira, pomwe inayo ikadali mphamvu yaying'ono yotayirira, kutayikira kwakukulu mu valavu.
Pali kuyerekeza valavu gulugufe atatu eccentric zitsulo molimba chisindikizo gulugufe valavu, valavu thupi ndi mpando kwa analumikizana zigawo zikuluzikulu, mpando kusindikiza pamwamba wosanjikiza pamwamba kuwotcherera kutentha, dzimbiri zosagwira aloyi zakuthupi.Mipikisano wosanjikiza zofewa mphete yosindikiza yokhazikika pa mbale ya valavu, valavu yagulugufeyi poyerekeza ndi valavu yagulugufe yachikhalidwe imakhala ndi kutentha kwakukulu, ntchito yowala, palibe kutseguka ndi kutseka, kutseka ndi torque ya njira yotumizira kuti ipereke chisindikizo, kupititsa patsogolo ntchito yosindikiza ya gulugufe ndikutalikitsa ubwino wa moyo wautumiki.

Nortech ndi m'modzi mwa otsogola opanga ma valve ku China omwe ali ndi chiphaso cha ISO9001.

Zogulitsa zazikulu:Valve ya Butterfly,Valve ya Mpira,Chipata cha Chipata,Onani Vavu,Globe Vavlve,Y-Strainers,Electric Acurator,Pneumatic Acurators .
