Farley Riggs supply RDI’s manufactured in-line swing check valve in 1″ and 2″ 1502 as well as 2″ 602 connections- 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 flow path and adds to the 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 a repair kit for all valves.
