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 andare sized at the option of the manufacturer.

Check valve creates the metal-to metal seal by the pressure of the medium, the more the pressure is, the better the sealing effect is.Anytimethe valve chamber can bear the pressure of the pipeline.The sealing face between valve core and valve body is welded with hard alloy with good abrasion resistance and anti-scour; the valve core is made of sulfide-resistance steel and the others adopt the process of hardness limit so the valve is ableto be used in H2S condition.
API 6A check valve(non-returning valve creates the metal-to- metal seal by the pressure of the medium, the more the pressure is, the better the sealing effect is.Anytime the valve chamber can bear the pressure of the pipeline. Valve body is machined of alloy steel forging with astronger machinery properties and reliable performance.
Bonnet is connected with valve body with bolt. The seals include the sealing ring inthe bonnet and the sealin 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.
