Instelbaar differentie-druk bypassventiel met schaal (instelbereik 1–6 mWS)

Productoverzicht

Dit instelbare differentie-druk bypassventiel zorgt voor constante bedrijfsomstandigheden in verwarmings- en koelcircuits met wisselende volumestromen. Het leidt overtollige doorstroming proportioneel terug naar het aantal gesloten verbruikers en beperkt zo de door de pomp gegenereerde differentiedruk.

Technische eigenschappen

Het ventiel is ontworpen voor water en glycoloplossingen met een maximaal glycolgehalte van 30% en een temperatuurbereik van 0 tot 110 °C. De maximale werkdruk bedraagt 10 bar; de instelbare ingrijpdruk ligt tussen 10 en 60 kPa (1–6 mWS).

Materialen

Behuizing en schuif bestaan uit messing EN 12165 CW617N, afdichtingen en O-ringen uit EPDM en schroefdraadafdichtingen uit asbestvrij NBR. Handgreep van ABS en veer van roestvrij staal garanderen duurzaamheid en weerstand tegen de gebruikelijke bedrijfsmedia.

Aansluitingen

Het ventiel is verkrijgbaar met schroefdraadaansluitingen volgens ISO 228-1: 3/4” IG voor AG met schroefverbinding of 1 1/4” IG voor AG met schroefverbinding. De keuze van de aansluiting is afhankelijk van de inbouwplaats en het leidingnet van de installatie.

Werking

Door het aanpassen van de veerkracht via het handwiel wordt het krachtenevenwicht op de schuif veranderd en daarmee de ingrijpdruk ingesteld. De schuif opent pas wanneer de differentiedruk de kracht van de contrastveer overschrijdt, waardoor een deelstroom naar de bypass wordt geleid en de druk in het betreffende leidinggedeelte wordt beperkt.

Bedrijf van de installatie

Het bypassventiel houdt de pompdruk dicht bij de nominale waarde, zelfs wanneer door gedeeltelijk sluiten van 2‑weg‑ventielen de doorstroming afneemt. Bij correct gedimensioneerd ventiel wordt de pomp onder alle bedrijfsomstandigheden, bijvoorbeeld bij volledig gesloten thermostaatventielen, op haar nominale bedrijfspunt gehouden.

Inbouwaanwijzingen

Het ventiel dient te worden ingebouwd op een plaats waar de differentiedruk representatief is voor het te regelen gedeelte en een storingsvrije bypass is gewaarborgd. Let op de juiste afdichtvlakken en passende schroefdraad en installeer voorfilters om vreemde deeltjes van de schuif weg te houden.

Onderhoud en bedrijfsveiligheid

Regelmatige visuele inspectie en indien nodig reiniging van het schuifgebied en de afdichtingen verlengen de levensduur. De veer en afdichtingen dienen bij langere stilstandstijden of na langere bedrijfsduur te worden gecontroleerd en bij slijtage te worden vervangen.

Voordelen en typische toepassingsgebieden

Het ventiel biedt betrouwbare drukbegrenzing, eenvoudige instelling via schaal en robuuste constructie voor het dagelijks gebruik in verwarming, klimaat en industrie. Typische toepassingsgebieden zijn systemen met veel thermostaat- of gemotoriseerde 2‑weg‑ventielen, retour- en distributietrajecten en pompregelkringen.

Adorable special occasion suit for boys
Size: 5, Color: Light Blue, Size: 5, Color: Light Blue
I ordered this 3-piece suit for my son and even though it’s currently a little too big for him, I couldn’t resist keeping it because it’s absolutely adorable! The quality really impressed me right out of the package. The fabric feels lightweight and breathable, which will be perfect for warmer weather, and it has a nice polished look without feeling stiff. The set comes with a blazer, vest, and pants, and each piece is very well made. I love the little details like the lapel on the jacket, the adjustable strap on the vest, and the adjustable waist on the pants, which will definitely help as he grows. It looks like a much more expensive suit than it actually is. Even though my son will have to grow into it, I’m already excited for him to wear it. I’m thinking it will be perfect for Easter next year or any special occasion. It’s such a cute outfit, and I love that the pieces can be mixed and matched for different looks. Overall, I’m really happy with this purchase and can’t wait to see him wearing it! The blue color goes well for any occasion and I may have to order my husband a suit in matching shade of blue so they can be twins. The size looks accurate for boys 5T. I took a picture to show the pants next to a pair of unwashed Oshkosh B’Gosh brand straight leg 5T boys denim jeans.

It’s a very **polished** look for events like weddings, family gatherings, or holiday parties. I also love that the **color options** are vibrant and fresh, perfect for summer. The suit is **easy to care for**—I was worried about linen wrinkles, but it’s held up well after a few washes, and the fabric still looks crisp. Overall, this **boys' linen summer suit** is an excellent purchase for any special occasion or just to make your little one look extra sharp during the summer months. **Comfortable, stylish, and durable**—highly recommend! 🌟👔

Nice summer suit for my son
Size: 6, Color: Light Green, Size: 6, Color: Light Green
I got this linen suit for my 7 year old son and it looks really nice on him. The set comes with the blazer, vest, and pants, which makes it look very polished when worn together. The material is lightweight and breathable, which is great for warmer weather. It has that classic linen look but still feels comfortable enough for kids to move around in. My son wore it for a few hours and didn’t complain about it being uncomfortable. I also like the little details like the pockets, the adjustable back on the vest, and the adjustable waistband on the pants. Those features really help with getting a better fit. Another nice thing is that you can mix and match the pieces. He can wear the vest and pants for a slightly more casual look or the full suit for more formal occasions. Overall it’s a really nice suit for kids, especially for events like weddings, family gatherings, or school events. My son looked great in it and it worked perfectly for the occasion.

Summer wedding kids suit
Color: Navy, Size: 10 Years, Color: Navy, Size: 10 Years
Bought this suit for my son in the 10 youth size and honestly was pleasantly surprised by the quality for the price. The navy color looks sharp and dressy without being too stiff or uncomfortable. The material has a little stretch, which helped it fit nicely and made it comfortable for him to move around in. The adjustable waist was a huge plus, especially for growing kids. It fit true to size overall, though the blazer sleeves were slightly long on my son. The pants had a nice slim look without being too tight. We paired it with white sneakers for a more modern look and it came out adorable. This would be perfect for weddings, graduations, concerts, communion, school events, or family photos. Overall, very happy with the purchase and would definitely buy again.

Very Modern Handsome Suit
Color: Grey, Size: 7 Years, Color: Grey, Size: 7 Years
This is an incredibly sharp looking suit for the little guy. Great price and features, too. I made a mistake in sizing up instead of down and first one was too sloppy on him and would need alterations. He is thin and very thin in the waist. There is a lot of adjustment with buttons in waistband and coat hides the bunching. This shirt and coat will easily take a fuller body than slim I believe. He loves posing in it and feels very classy. Best purchase for a formal suit that will last longer than most kids clothes size wise. Felt bad about returning but careful folding and packing got it good as new.
