Key Specifications / Features
Our Duplex Stainless Steel Check Valve, manufactured in China, features a robust dual plate design and is made from ASTM A890 5A material. This 8-inch (DN200) valve is rated for Class 150 LB and complies with API 594 and API 6D standards. It is equipped with double flanged ends for easy installation and secure integration into pipeline systems.
Constructed with a one-piece body, central pin, and two spring-loaded plates, this valve efficiently allows fluid flow in one direction while effectively blocking reverse flow. Compared to conventional swing check valves, our dual plate design significantly reduces both weight and length, resulting in cost and space savings for your piping system. Ideal for a range of industrial applications, including water treatment, oil and gas, and chemical processing, this valve ensures reliable performance and durability.
