3, valavu ya mpira: imapangidwa kuchokera ku valavu ya pulagi, kutsegulira ndi kutseka mbali zake ndi mpira, pogwiritsa ntchito mpira kuzungulira tsinde axis kuzungulira 90 ° kuti azindikire cholinga chotsegula ndi kutseka.Vavu ya mpira imagwiritsidwa ntchito kwambiri podula, kugawa ndikusintha komwe kumayendera sing'anga mupaipi.Valve ya mpira yokhala ndi mawonekedwe a v imakhalanso ndi ntchito yabwino yoyendetsera kayendetsedwe kake.
Ubwino:
(1) Ndi kukana otsika (kwenikweni 0);
② Chifukwa sichigwira ntchito (palibe mafuta), chitha kugwiritsidwa ntchito modalirika pazambiri zowononga ndi madzi otentha otentha;
Mu osiyanasiyana kuthamanga ndi kutentha, akhoza kukwaniritsa kusindikiza kwathunthu;
④ Imatha kuzindikira kutsegulira ndi kutseka mwachangu, ndipo nthawi yotsegulira ndi kutseka yazinthu zina ndi 0.05-0.1s kuti zitsimikizire kuti zitha kugwiritsidwa ntchito pamakina opangira bedi loyesera.Kutsegula ndi kutseka kwa valve, kugwira ntchito popanda mphamvu;
(5) Zigawo zotsekera zozungulira zimatha kukhazikitsidwa pamalire;
⑥ Sing'anga yogwirira ntchito mbali zonse za chisindikizo ndi yodalirika;
⑦ Ikatsegulidwa kwathunthu ndi kutsekedwa kwathunthu, malo osindikizira a mpira ndi mpando amakhala otalikirana ndi sing'anga, kotero sing'anga kupyolera mu valavu pa liwiro lalikulu sichidzachititsa kukokoloka kwa malo osindikizira;
⑧ mawonekedwe yaying'ono, kulemera kopepuka, imatha kuonedwa ngati mawonekedwe a valve otsika kutentha kwapakati;
⑨ Symmetrical valve body, makamaka welded valavu kapangidwe kake, amatha kupirira kupsinjika kwa payipi bwino;
⑩ Zigawo zotsekera zimatha kupirira kusiyana kwakukulu pakutseka.(11) Mpira valavu kuwotcherera thupi, akhoza mwachindunji m'manda pansi, kotero kuti mbali zamkati za valavu si kukokoloka, moyo utumiki wa zaka 30, ndi valavu abwino kwa mapaipi mafuta ndi gasi.
Zoyipa:
(1) Chifukwa chachikulu valavu mpando kusindikiza mphete zakuthupi ndi ptfe, ndi inert pafupifupi mankhwala onse, ndipo ali ndi makhalidwe athunthu ang'onoang'ono mikangano koyefishienti, ntchito khola, si kosavuta kukalamba, osiyanasiyana kutentha ndi ntchito yabwino yosindikiza.Koma maonekedwe a thupi la PTFE, kuphatikizapo mkulu coefficient wa kukula, tilinazo ozizira otaya ndi osauka matenthedwe madutsidwe, amafuna kuti mpando chisindikizo kupangidwa mozungulira makhalidwe amenewa.Chotsatira chake, pamene chinthu chosindikizira chikuwumitsa, kudalirika kwa chisindikizo kumawonongeka.Komanso, kukana kutentha kwa PTFE ndi otsika ndipo angagwiritsidwe ntchito pansi pa chikhalidwe cha zosakwana 180 ℃.Pamwamba pa kutentha uku, zinthu zosindikizira zidzakalamba.Pogwiritsa ntchito nthawi yayitali, nthawi zambiri sagwiritsidwa ntchito pa 120 ℃.
② Kuwongolera kwake kumakhala koyipa kuposa valavu yapadziko lonse lapansi, makamaka valavu ya pneumatic (kapena valavu yamagetsi).

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