Oil&Gas Check Valve Description API6D Flange End Swing Type Check Valve is used to prevent medium backflow in the pipeline. The medium passes through the valve in a straight line to achieve the minimum pressure drop. We use high-quality flange to make this product. This material has good mechanical and chemical properties. First of all, the excellent corrosion resistance makes the product not easy to be eroded by the medium in the pipe. Secondly, the product has good rust resistance. General workpieces will rust when they are exposed to wet media for a long time, and the excellent rust resistance of this product effectively avoids this situation. Excellent products, reliable quality and effective service have won the recognition of our customers. We conscientiously fulfill our cultural and social obligations, innovate and promote public welfare undertakings, and consciously undertake more social obligations.
