Njengomenzi wevalvu ye-actuator, i-COVNA yenza iivalvu kumashishini ahlukeneyo kwizisombululo ezizenzekelayo.Nantoni na efuna uncedo, qhagamshelanasales@covnavalve.com
Kweli nqaku, sinentshayelelo emfutshane malunga neevalvu zeshishini leoli kunye negesi.Kubandakanya ivalve esebenzayo kunye nevalve yesandla kwireferensi yakho.Ndiyathemba ukuba iya kukunceda ukhethe ivalve yeprojekthi yakho.

1. Iivalvu zokuvala kwaye uqalise imidiya

Iivalve ezininzi zinomsebenzi wokusika kunye nokuqala, ngoko ke unokukhetha ivalve yesango, ivalve yokumisa, ivalve yebhola, ivalve yebhabhathane, ivalve yeplagi njalo njalo.Kunconywa ukuba ukhethe i-valve efanelekileyo ngokwemiqathango ethile yesicelo.

2. Iivalvu zeulawulo lokuqukuqela

Iivalvu zeglobhu zikulungele kakhulu ukulawula ukuhamba.Iivalve zebhola, iivalve zebhabhathane, kunye neeplagi zeplagi nazo zingasetyenziswa ukulawula ukuhamba, kodwa ukuchaneka kuphantsi.

3.Iivalvu zokubuyisela umva kunye nokujika

Ngokweemfuno zokubuyisela umva kunye ne-shunting, olu hlobo lwevalve kufuneka lube ne-3 okanye ngaphezulu kweziteshi.Iivalve zeplagi kunye neevalve zebhola zifaneleke ngakumbi kule njongo.Kodwa kwiimeko ezikhethekileyo, nje ukuba iivalve ezimbini okanye ngaphezulu zixhunyiwe ngokufanelekileyo omnye komnye, zingasetyenziselwa ukubuyisela umva kunye nokucima.

4. Iivalvu zemidiya ezinamasuntswana amisiweyo

Xa kukho amasuntswana amisiweyo phakathi, ivalve yesango kunye nevalve yesango lemela ingasetyenziswa.Zinempembelelo yokucima kwindawo yokutywinwa ngexesha lokuvula kunye nokuvala inkqubo, ngoko ke zifanelekile ukusetyenziswa kwimidiya kunye neengqungquthela ezimisiwe.
