2" 150LB Stainless Steel A351 CF8 Flange End Swing Check Valve
Design Features
Swing Type Structure: The valve disc rotates around the axis of the valve seat, with quick opening and closing actions, low fluid resistance, and can effectively prevent the backflow of media.
Full Bore Design: The passage inside the valve body is consistent with the inner diameter of the pipeline, ensuring the smooth flow of media, reducing pressure loss, and improving the overall efficiency of the system.
Reliable Sealing Performance: The valve disc and valve seat are precisely machined and use high-quality sealing materials to ensure a good sealing effect under normal working pressure and prevent media leakage.
Strong Corrosion Resistance: The stainless steel of A351 CF8 material has excellent anti-corrosion performance, can resist the erosion of various chemical media, extend the service life of the valve, and reduce maintenance costs.
Compliance with International Standards: Its design and manufacture comply with international standards such as API 6D and BS 1868, ensuring the quality and reliability of the product and meeting the engineering specification requirements of different countries and regions.
