4. Gulu ndi galimoto mode
(1) Valavu yodziyimira imatanthawuza valavu yomwe sifunikira mphamvu yakunja kuti iyendetse, koma imadalira mphamvu ya sing'anga yokha kuti valavu isunthe. Monga valavu chitetezo, valavu kuchepetsa kuthamanga, valavu kukhetsa, valavu cheke, valavu yowongolera basi, etc.
(2) Valve yoyendetsa mphamvu: Valavu yoyendetsa mphamvu imatha kuyendetsedwa ndi magwero osiyanasiyana amagetsi.
(3) Vavu yamagetsi: valavu yoyendetsedwa ndi mphamvu yamagetsi.
Vavu ya pneumatic: Vavu yoyendetsedwa ndi mpweya woponderezedwa.
valavu yoyendetsedwa ndi mafuta: valve yoyendetsedwa ndi kuthamanga kwamadzi monga mafuta.
Kuphatikiza apo, pali kuphatikiza kwa njira zingapo zomwe zili pamwambazi, monga ma valve amagetsi amagetsi.
(4) Valavu yamanja: valavu yamanja mothandizidwa ndi gudumu lamanja, chogwirira, lever, sprocket, kupita ndi valavu. Pamene mphindi yotsegulira ma valve ndi yayikulu, gudumuli ndi chochepetsera mphutsi akhoza kukhazikitsidwa pakati pa gudumu lamanja ndi tsinde la valve. Ngati ndi kotheka, mutha kugwiritsanso ntchito cholumikizira chapadziko lonse lapansi ndikuyendetsa shaft kuti mugwire ntchito mtunda wautali.
5. Gulu molingana ndi m'mimba mwake mwadzina
(1) Vavu yaing'ono yaing'ono: valve yokhala ndi DN 40mm.
(2)Zapakativalavu m'mimba mwake: valavu ndi m'mimba mwake mwadzina DN wa 50 ~ 300mm. valve
(3)Chachikuluvalavu m'mimba mwake: vavu mwadzina DN ndi 350 ~ 1200mm valavu.
(4) Valavu yayikulu kwambiri: valve yokhala ndi DN 1400mm.
6. Kugawa ndi mawonekedwe
(1) Valovu yotsekera: gawo lotsekera limayenda pakati pa mpando wa valve;
(2) stopcock: mbali yotseka ndi plunger kapena mpira, kuzungulira pakati pa mzere wokha;
(3) Mawonekedwe a chipata: gawo lotsekera limayenda pakati pa mpando wopindika wa valve;
(4) Valavu yotsegulira: gawo lotseka limazungulira mozungulira kunja kwa mpando wa valve;
(5) Vavu ya butterfly: chimbale cha chidutswa chotsekedwa, chozungulira mozungulira pampando wa valve;
7. Gulu ndi njira yolumikizira

(2)Valve yolumikizana ndi flange: valavu thupi ndi flange, ogwirizana ndi chitoliro flange.
(3) Kuwotcherera valavu kugwirizana: valavu thupi ali kuwotcherera poyambira, ndipo chikugwirizana ndi kuwotcherera chitoliro.
(4)Wafervalve yolumikizira: thupi la vavu lili ndi chomangira, cholumikizidwa ndi chitoliro.
(5) Vavu yolumikizira manja: chitoliro chokhala ndi manja.
(6) Gwirizanitsani valavu yolumikizana: gwiritsani ntchito mabawuti kuti mutseke valavu ndi chitolirocho palimodzi.
8. Gulu ndi zida za thupi la valve
(1) Valavu yachitsulo: thupi la valve ndi ziwalo zina zimapangidwa ndi zitsulo. Monga valavu yachitsulo, valavu yachitsulo, valavu yachitsulo, valavu yachitsulo, valavu yamkuwa, valavu ya aluminiyumu, kutsogolera
