Der findes to typer kontraventiler: frit bevægelige og styrede. De bruges typisk i systemer, der kræver envejs flow, eller som beskyttelse mod tilbageløb. Derudover kan kontraventiler anvendes til at forhindre store væsketab ved rørbrud.

En kontraventil er en uundværlig komponent, der sikrer, at vand kun løber i én retning i et rørsystem. Dette er især vigtigt for at forhindre tilbageløb af vand, der kan forårsage skader eller kontaminering i vandforsyningen. Hos Lauridsen Group tilbyder vi et bredt udvalg af kontraventiler, der passer til forskellige behov og applikationer.
Hos Lauridsen Group finder du et stort udvalg af kontraventiler til vand. Vores produkter kombinerer høj kvalitet og pålidelig funktionalitet, hvilket sikrer, at dit vandsystem fungerer optimalt. Vi tilbyder blandt andet:
Disse ventiler er specielt designet til at forhindre tilbageløb i vandforsyningssystemer. De er nemme at installere og giver pålidelig beskyttelse mod uønskede flowretninger.
Disse ventiler fungerer ved, at en kugle bevæger sig op og ned inden i ventilen, hvilket sikrer en effektiv envejsfunktion. Kuglekontraventiler er ideelle til applikationer, hvor der er risiko for vandslag, da de er robuste og pålidelige.
Udstyret med en disk, der svinger væk for at tillade flow og lukker for at forhindre tilbagestrømning, er kontraklapventiler velegnede til større rørsystemer, hvor effektiv lukning er kritisk.
Vores kontraventiler findes i forskellige størrelser, herunder 3/4" og 1/2". Disse størrelser er perfekte til både private og kommercielle applikationer, hvor der er behov for præcis kontrol over vandflowet.
Med en kontrollerbar kontraventil får du mulighed for at overvåge og justere ventilens funktion. Dette er ideelt til mere komplekse installationer, hvor fleksibilitet og kontrol er nødvendige.
Stopventiler sikrer, at du nemt kan afbryde vandtilførslen ved behov. Dette er en praktisk og sikker løsning til vedligeholdelse eller akutte reparationer.
Vi forstår, hvor vigtigt det er at have pålidelige og holdbare produkter til dine vandsystemer. Her er nogle af fordelene ved vores kontraventiler:
Valget af den rette kontraventil afhænger af flere faktorer:
