Muenzaniso wekutanga wakafanana nevharuvhu yebhorandiyo vharuvhu yakabvumidzwa naJohn Warren muna 1871. Ivharuvhu yakagadzikwa nesimbi ine bhora remhangura nechigaro chemhangura. Warren akazopa patent yake yekugadzira vharuvhu yebhora remhangura kuna John Chapman, mukuru weChapman Valve Company. Chero chikonzero chipi zvacho, Chapman haana kumbobvira aisa dhizaini yaWarren mukugadzirwa. Pane kudaro, iye nevamwe vagadziri vevharuvhu vanga vachishandisa magadzirirwo ekare kwemakore mazhinji.

Mavharuvhu ebhora, anozivikanwawo semavharuvhu ebhora, akazoshanda panguva yeHondo Yenyika II. Munguva iyi, mainjiniya akaagadzira kuti ashandiswe muhurongwa hwemafuta endege dzehondo. Mushure mekubudirira kwemavharuvhu ebhoraMuHondo Yenyika II, mainjiniya akashandisa mavharuvhu ebhora mukushandiswa kwemaindasitiri.

Imwe yenzira dzakakosha dzakaitwa nemavharuvhu ebhora muma1950 yaive kugadzirwa kweTeflon uye kushandiswa kwayo sechigadzirwa chevharuvhu yebhora. Mushure mekubudirira kwekugadzirwa kweTeflon, mabhizinesi mazhinji akadai seDuPont akakwikwidzana kuti awane kodzero yekuishandisa, nekuti aiziva kuti Teflon yaigona kuunza mabhenefiti makuru pamusika. Pakupedzisira, makambani anopfuura rimwe chete akakwanisa kugadzira mavharuvhu eTeflon. Mavharuvhu ebhora eTeflon anochinjika uye anogona kugadzira zvisimbiso zvakanaka munzira mbiri. Nemamwe mashoko, anotungamira kumativi maviri. Haapindiwo pakudonhedza mvura. Muna 1958, Howard Freeman ndiye aive mugadziri wekutanga kugadzira vharuvhu yebhora ine chigaro cheTeflon chinochinjika, uye dhizaini yake yakapihwa patent.

Nhasi, mavharuvhu ebhora akagadzirwa nenzira dzakawanda, kusanganisira kuenderana kwezvinhu zvawo uye mashandisirwo aanogona kuita. Pamusoro pezvo, vanogona kushandisa CNC machining uye computer programming (senge Button model) kugadzira mavharuvhu akanakisa. Munguva pfupi iri kutevera, vagadziri vemavharuvhu ebhora vachakwanisa kupa sarudzo dzakawanda dzezvigadzirwa zvavo, kusanganisira kugadzirwa kwearuminiyamu, kusakara kushoma uye kugona kukuru kwekubvisa mavharuvhu, izvo zvinobvumira vashandisi kupfuudza huwandu hunochinja hwemvura nevharuvhu nepadanho rekuyerera kushoma.

Chinangwa chevharuvhu yebhora ndechekudzora kuyerera kwemvura. Vanogona kuita izvi nenzira dzakawanda. Vanogona kugadzirisa mamwe marudzi emavharuvhu ekuyerera kwemvura kushoma, kudzivirira kudzokera shure kwemavharuvhu nekubatanidza kwekutarisa swing, kuparadzanisa sisitimu, uye kuvharisa zvakakwana kune vanobata magiya.

Nekuti anogona kudzorwa nemaoko kana nemagetsi, mavharuvhu ebhora anogona kushandiswa muzvirongwa zvakasiyana-siyana.

Kazhinji, mavharuvhu ebhora anoshandiswa kuvhura nekuvhara mapaipi ane zvinhu zvakasimba zvakasungirirwa, slurry, liquids kana gasi. Mamwe mashandisirwo anowanzoitwa mavharuvhu ebhora anosanganisira masisitimu emapaipi, michina, uye maturusi muindasitiri dzese dzinotakura mvura. Unogona kuawana chero kupi kubva pasi pefekitori kusvika papombi mumba mako. Maindasitiri anoshandisamavharuvhu ebhorazvinosanganisira kugadzira zvinhu, migodhi, mafuta negesi, kurima, kudziyisa nekutonhodza, mapaipi emaindasitiri neemumba, mvura, zvinhu zvevatengi, kuvaka, nezvimwewo
