Valve ea lefats'e ke eng?
Valo ea lefats'ee etselitsoe le ho etsoa ho latela maemo a mehleng a Jeremane, DIN le maemo a kajeno a Europe EN13709.e sebelisoa haholo-holo linaheng tsa European Union.

Ho buleha ha setulo ho fetoha ka ho lekana le leeto la disc e leng se loketseng mesebetsi e amanang le taolo ea phallo. Li-valve tsa DIN-EN Globe li loketse haholo 'me li sebelisoa haholo ho laola kapa ho emisa phallo ea metsi kapa khase ka phaepheng bakeng sa ho thiba le ho laola phallo ea metsi 'me hangata li sebelisoa liphaepheng tse nyane.
eLi-valve tsa lefats'ee ka sebelisoa bakeng sa merero ea ho thiba le ho thiba. Mekhahlelo e mengata ea li-valve tse lutseng motho a le mong e sebelisa kaho ea sekhoa kapa mokhoa oa ho boloka serethe sa setulo, e fana ka tataiso ea polaka ea li-valve, le ho fana ka mokhoa oa ho theha litšobotsi tse itseng tsa phallo ea li-valve. E ka boela ea fetoloa habonolo ka ho fetola likarolo tsa trim ho fetola tšobotsi ea phallo kapa ho fana ka phallo e fokotsehileng ea bokhoni, ho fokotsa lerata, kapa ho fokotsa kapa ho felisa cavitation.
