Ma valve omangirira ndi zigawo zofunika zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana ndi ntchito. Ma valve awa amapangidwa kuti aziwongolera kutuluka kwa madzi kudzera pamapaipi, zomwe zimapangitsa kuti pakhale kuwongolera kosavuta komanso koyenera. Ndi mapangidwe awo osavuta koma ogwira mtima, ma valve a pulagi ndi chisankho chodziwika pakati pa akatswiri ambiri.

Ntchito yayikulu ya valavu ya pulagi ndikuyambitsa, kuyimitsa kapena kutsitsa kutuluka kwa zinthu. Amakhala ndi pulagi ya cylindrical kapena conical yokhala ndi dzenje (lotchedwa doko) pakati. Potembenuza tambala mu thupi la valve, doko likhoza kugwirizanitsidwa kapena kutsekedwa ku chitoliro, motero kulamulira kutuluka. Makinawa amapatsa valavu ya pulagi dzina lake lapadera.

Chimodzi mwazabwino zazikulu za mavavu a pulagi ndikutha kwawo kupereka kuwongolera kwathunthu. Pulagi ikatsegulidwa kwathunthu, kuthamanga kwamadzi kumakulitsidwa, zomwe zimapangitsa kuti madzi aziyenda bwino komanso mopanda malire. Mosiyana ndi zimenezo, kutseka choyimitsa kumayimitsa kutuluka kwathunthu. Kuwongolera uku ndikofunikira pamafakitale omwe amafunikira kuwongolera bwino kwa kayendetsedwe kake, monga mafuta ndi gasi, kuthira madzi, ndi zomera zamankhwala.

Mavavu a pulagi amadziwikanso kuti ndi olimba komanso odalirika. Amapangidwa kuchokera ku zinthu zolimba monga chitsulo chosapanga dzimbiri, chitsulo cha kaboni kapena chitsulo chosungunuka, kuonetsetsa kuti atha kupirira zovuta zogwirira ntchito. Izi zimawapangitsa kukhala abwino kuti agwiritsidwe ntchito pamakina othamanga kwambiri kapena malo okhala ndi zinthu zowononga. Ndi chisamaliro choyenera, ma valve a pulagi amatha kukhala ndi moyo wautali wautumiki, kuchepetsa kufunika kosinthidwa pafupipafupi komanso kuchepetsa nthawi yopuma.

Kuonjezera apo, ma valve amapulagi amakhala ndi mphamvu zochepa zamadzimadzi akamatseguka. Mbaliyi ndi yabwino pochita ndi viscous kapena abrasive media chifukwa imachepetsa mwayi wotseka kapena kuwononga valavu. Njira yowongoka yomwe imapangidwa ndi pulagi yotseguka imalola kuti pakhale njira yosalala yamadzimadzi, kuteteza kutsika kosafunika kofunikira ndikuwongolera magwiridwe antchito.

Ubwino wina wa mavavu a pulagi ndi kusinthasintha kwawo. Zitha kugwiritsidwa ntchito pazinthu zosiyanasiyana kuphatikiza ma switching ndi throttling services. Ma valve awa ndi oyenera kugwira ntchito zosiyanasiyana zamadzimadzi monga zakumwa, mpweya, slurries ndi ufa. Kuphatikiza apo, mavavu a pulagi ndi oyenera kutentha kwakukulu, kuwapangitsa kukhala oyenera njira zotentha komanso zozizira kwambiri.

Ngakhale valavu ya pulagi ili ndi ubwino wambiri, imakhalanso ndi malire. Chimodzi mwazovuta zawo ndikutha kutayikira mukatsekedwa. Chifukwa cha mapangidwe, nthawi zambiri pamakhala kusiyana kochepa pakati pa pulagi ndi mpando wa valve, zomwe zingayambitse kutayikira. Komabe, kupita patsogolo kwaukadaulo kwathandizira kuthetsa vutoli, ndipo ma valve a pulagi amakono nthawi zambiri amaphatikiza zinthu monga zisindikizo ziwiri kapena zokutira zapadera kuti achepetse kutayikira.

Pomaliza, ma valve amapulagi akhala gawo lofunikira m'mafakitale ambiri chifukwa chakuchita bwino, kulimba komanso kusinthasintha. Kukhoza kwawo kuwongolera bwino kayendedwe ka madzimadzi kumawapangitsa kukhala chisankho choyamba kwa akatswiri omwe amafunikira malamulo odalirika, oyendetsa bwino. Pamene mapangidwe ndi teknoloji ikupitirirabe patsogolo, ma valve amapulagi akupitirizabe kusinthika, kupereka ntchito yabwino komanso kukwaniritsa zosowa zamakampani.
