Deze roestvrijstalen, corrosiebestendige veer zorgt ervoor dat de juiste sluitkracht op de interne klep terugkeert, zodat de terugslagklep de terugstroom in de filter- en behandelingscircuits van het zwembad betrouwbaar blijft tegenhouden.<\/p>\n<h3>Originele veer voor terugslagkleppen uit de Clear-serie met een diameter van 50<\/h3>\n<p>Bij de terugslagkleppen uit de AstralPool Clear-serie wordt de interne klep ondersteund door een veer, waardoor deze snel terugkeert naar de gesloten stand wanneer de pomp stopt of wanneer de stroming omkeert. De AstralPool Clear Series-klepveer D50 is vervaardigd volgens dezelfde afmetingen en eigenschappen als de in de fabriek gemonteerde veer, waardoor een correcte beweging van de klep en een veilige afsluiting onder alle normale bedrijfsomstandigheden worden gegarandeerd.<\/p>\n<p>Het gebruik van de juiste referentieveer is essentieel om de terugslagfunctie te behouden. Een te zwakke veer kan terugstroming toestaan, terwijl een onjuiste of te sterke veer het drukverlies kan vergroten of voortijdige slijtage van de klep en de zitting kan veroorzaken.<\/p>\n<h3>Wanneer moet de klepveer worden vervangen?<\/h3>\n<p>Na verloop van tijd wordt de klepveer blootgesteld aan voortdurende beweging, chloorhoudend water en, in veel gevallen, zout water. Zelfs met beschermende coatings kan dit leiden tot verlies van elasticiteit of plaatselijke corrosie. Het wordt aanbevolen om het versleten onderdeel te vervangen door een nieuwe AstralPool Clear Series-klepveer D50 zodra u het volgende opmerkt:<\/p>\n<ul>\n<li>Terugstroming door de leiding wanneer de pomp stopt.<\/li>\n<li>Een klep die langzaam sluit of niet goed aansluit.<\/li>\n<li>Zichtbare corrosie, vervorming of breuk van de veer tijdens de inspectie.<\/li>\n<\/ul>\n<p>Door op het juiste moment een nieuwe veer te plaatsen, kunnen circulatieproblemen worden voorkomen, zoals het verlies van de zuigkracht, ongewenst leeglopen van leidingen of terugstroming door filters, verwarmingselementen en chloorapparaten.<\/p>\n<h3>Eenvoudig onderhoud dankzij het ontwerp van de Clear-serie<\/h3>\n<p>Het ventielhuis van de Clear Series is volledig transparant en voorzien van een afneembaar deksel met schroefdraad, waardoor de interne veer gemakkelijk bereikbaar is. Zodra het deksel is losgeschroefd en de klepconstructie is verwijderd, kan de AstralPool Clear Series-ventielveer D50 worden vervangen zonder dat de leidingen hoeven te worden doorgesneden of aangepast.<\/p>\n<ul>\n<li>Geschikt voor terugslagkleppen uit de Clear-serie D50 met transparante behuizing.<\/li>\n<li>De vervanging van de veer kan worden uitgevoerd tijdens de routine-reiniging van de klep en de afdichtingen.<\/li>\n<li>Er hoeven geen wijzigingen te worden aangebracht aan de PVC-behuizing of de koppelingen.<\/li>\n<\/ul>\n<p>Dankzij deze onderhoudsvriendelijke opzet kunnen zwembadtechnici en ervaren eigenaren de werkzaamheden snel uitvoeren, waardoor de stilstandtijd van het systeem wordt beperkt en het hydraulische circuit in optimale staat blijft.<\/p>\n<h3>Aanbevelingen voor de installatie<\/h3>\n<p>Een correcte montage van de AstralPool Clear Series-klepveer D50 zorgt voor een soepele en betrouwbare werking van de terugslagklep. Alle werkzaamheden moeten worden uitgevoerd terwijl de pomp is uitgeschakeld en de leiding drukloos is.<\/p>\n<ul>\n<li>Sluit de afsluitkleppen en laat de druk ontsnappen voordat u de terugslagklep opent.<\/li>\n<li>Draai de borgring los en verwijder het doorzichtige deksel volgens de instructies van de Clear Series.<\/li>\n<li>Haal de klepconstructie eruit, verwijder de oude veer en monteer de nieuwe D50-veer op de oorspronkelijke plaats.<\/li>\n<li>Controleer of de klep soepel beweegt en stevig terugkeert naar de gesloten stand.<\/li>\n<li>Zet de klep weer in elkaar, draai het deksel gelijkmatig vast en controleer of er geen lekken zijn en of de klep goed sluit wanneer de pomp stopt.<\/li>\n<\/ul>\n<p>Controleer na de vervanging tijdens de start- en stopcycli of de klep bij doorstroming volledig opengaat en snel en volledig sluit wanneer de doorstroming stopt, om er zeker van te zijn dat de nieuwe veer correct functioneert.<\/p>","protected":false},"excerpt":{"rendered":"<p>AstralPool Clear Series valve spring D50 The AstralPool Clear Series valve spring D50 is the original replacement spring for Clear Series check valves with 50 mm connections.
