Swing check valves

APPLICATION

Swing check valves are protective devices in pipelines and pipe systems for the transport of liquid fluids.
They are used to prevent the return flow of the working fluid, and their action is automatic.
They are most widely used in drinking water distribution systems and irrigation, wastewater treatment and transport systems, as well as in district heating systems.
The non-return (check )valves allow flow in only one direction, which is why during installation you should pay attention to the fact that the direction of the arrow on the check valve housing corresponds to the direction of movement of the working fluid in the specific pipeline.

FURTHER INFORMATION

Povratne klapne izrađujemo sa zapornim telom koje rotira oko osovine koja tangira zaporno telo. Na osovini je ugrađena torziona opruga odgovarajućeg momenta koja omogućava da povratna klapna dobro zaptiva i pri malim povratnim pritiscima.
Zaptivna površina na kućištu povratne klapne navaruje se elektrodom otpornom na koroziju, a zaptivanje se vrši preko gumenog prstena smeštenog u kanalu zapornog tela. Povratne klapne izrađujemo bez prirubnica, te se iste montiraju između cevnih prirubnica sa odgovarajućim prirubnicama.
Nazivni prečnik se kreće od DN 50 do DN 500 (mm), a pritisci od NP 2,5 do NP 16 (bar).

Kućište i zaporno telo izrađujemo od konstrukcionih čelika zavarivanjem, a osovinu od čelika otpornog na koroziju. Zaptivni elementi za temperaturu fluida do 80°C izrađuju se od EPDM-a, a za temperaturu do 150°C od specijalnog EPDM-a.
