API Spec 6A Wellhead Check Valve for Oil Drilling
Product Introduction
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.
Bonnet is connected with valve body with bolt. The seals include the sealing ring in the bonnet and the seal in the valve body, which makes a very small gap between valve body and bonnet, thus minimizing corrosion of corrosive medium to bolt and screw hole and reducing bolt loading.
