Manufactured according to API Spec 6A "Equipment Specification of Wellhead & X`mas tree" and matched and interchangeable with any equipment which conforms to API 6A specification. Check Valve (API Spec 6A): It 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 a stronger machinery properties and reliable performance. Bonnet is connected with valve body with bolt, the seals include the sealing ring in the bonnet and the seal in the valve body; 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 able to be used in H2S condition. The sealing-face of the valve core and the valve body is bead-welded with carbide, plus rubber seals, which has The swing check valves manufactured by our company are available in ***0psi, ***0psi and ***0psi working pressure, nominal size from 1`through 8`, material classes from AA through FF, product specification levels (PSL) from 1 through 3 and performance requirement (PR) 1.
