Valavu yowongolera madzi ndi valavu yoyendetsedwa ndi madzi, yomwe imakhala ndi valavu yayikulu ndi cholumikizira chake cholumikizidwa, valavu yoyendetsa, valavu ya singano, valavu ya mpira ndi choyezera kuthamanga. Malinga ndi zolinga zosiyanasiyana, ntchito ndi malo ogwiritsira ntchito, imatha kupangidwa kukhala valavu yoyandama yoyendetsedwa ndi remote control, valavu yochepetsera kuthamanga, valavu yowunikira kutseka pang'onopang'ono, valavu yowongolera kuyenda, valavu yochepetsera kuthamanga, valavu yowongolera kuthamanga, valavu yowongolera magetsi ya hydraulic, ndi zina zotero.

Valavu yowongolera ya hydraulic imagawidwa m'magulu a mtundu wa diaphragm ndi mtundu wa piston. Mfundo yogwirira ntchito ndi yofanana. Zonsezi zimayendetsedwa ndi kusiyana kwa kuthamanga pakati pa malo apamwamba ndi otsika, ndipo zimayendetsedwa ndi valavu yoyendetsa, kotero kuti ntchito yosiyanitsa ya diaphragm (piston) hydraulic ikhoza kusinthidwa yokha ndi mphamvu ya hydraulic, kotero kuti diski yayikulu ya valve ikhoza kutsegulidwa kapena kutsekedwa kwathunthu kapena mu mkhalidwe wosinthira. Madzi opanikizika omwe amalowa mu chipinda chowongolera pamwamba pa diaphragm (piston) akatulutsidwa mumlengalenga kapena m'dera lotsika la kuthamanga, kuthamanga komwe kumagwira ntchito pansi pa diski ya valve ndi pansi pa diaphragm kumakhala kwakukulu kuposa kuthamanga komwe kuli pamwambapa, kotero kankhirani diski yayikulu ya valve pamalo otseguka kwathunthu; Pamene madzi opanikizika omwe ali mu chipinda chowongolera pamwamba pa diaphragm (piston) sangathe kutulutsidwa mumlengalenga kapena m'dera lotsika la kuthamanga, kuthamanga komwe kumagwira ntchito pa diaphragm (piston) kumakhala kwakukulu kuposa kuthamanga komwe kuli pansipa, kotero diski yayikulu ya valve idzakanikizidwa pamalo otsekedwa kwathunthu; Pamene mphamvu ya kupanikizika m'chipinda chowongolera pamwamba pa diaphragm (piston) ili pakati pa mphamvu yolowera ndi mphamvu yotulutsira, diski yayikulu ya valavu imakhala mu mkhalidwe wowongolera, ndipo malo ake owongolera amadalira mphamvu yowongolera yolumikizana ya valavu ya singano ndi valavu yoyendetsera yosinthika mu dongosolo la conduit. Vavu yoyendetsera yosinthika imatha kutsegula kapena kutseka doko lake laling'ono la valavu kudzera mu mphamvu yotulutsira yotsika komanso ndi kusintha kwake, kuti isinthe mphamvu ya kupanikizika m'chipinda chowongolera pamwamba pa diaphragm (piston) ndikuwongolera malo osinthira a diski ya valavu yozungulira.

Nortech ndi m'modzi mwa opanga ma valve otsogola ku China omwe ali ndi satifiketi ya ISO9001 yapamwamba.
