●NOM Valve currently manufactures an in-line swing check valve in 1” & 2” 1502 as well as 2” 602-standard and Sour (H2S) service.

●The proven flapper and seat design includes an o-ring on the face of the seat to assure tight sealing under all operating conditions. This o-ring is located on the downstream side of the seat, not on the flapper, which keeps it out of the direct flowpath and adds to service life.

●The flapper and seat are titanium-nitrided to assure long service life even in abrasive conditions.

●The seat and flapper are designed as separate components, which, along with the seals are available as arepair kit for all valves.
