High Pressure Natural Gas Swing Check Valve for Wellhead
Product Overview
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. Anytime the 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 able to be used in H2S condition.
The product is designed and manufactured according to API Spec 6A "Equipment Specification of Well-head & X'mas tree" and matched and interchangeablewith any equipment which conforms to API 6Aspecification.
