API 6D Dual Check Valve, 8 Inch, Class 900 LB, ASTM A890 5A
Model Number: 1842086
Key Specifications / Features
Our API 6D Dual Plate Check Valves are engineered for excellence. These 8-inch, Class 900 LB valves, crafted from durable ASTM A890 5A duplex stainless steel, feature a compact wafer connection. As spring-loaded non-return valves, they ensure one-way flow, effectively preventing backflow in pipelines. The design includes a robust one-piece body, a central pin, and dual plates secured by the pin and spring-loaded. This configuration allows fluid to flow smoothly in one direction while blocking reverse flow. Compared to conventional swing check valves, our dual plate check valves offer significant reductions in weight and length, leading to cost savings and space efficiency in piping systems.
