API 6A Swing Check Valve for Oilfield Wellhead

Product Overview

Check valves are of the swing and lift check types. The valves may be full-opening or reduced-opening and are used to permit fluid flow in only one direction. All full-opening valves have round passageways through the body and seats. Regular-lift and swing check valves are customarily made with reduced bores through the seat and are sized at the option of the manufacturer.

The sealing face between valve core and valve bodyis welded with hard alloy with good abrasion resistanceand anti-scour; the valve core is made of sulfide-resistance steel and the others adopt the process of hard-ness limit so the valve is able to be used in H2S condition.
