Cameron 9D-511-035027-121 Flange Mount Swing Check Valve

Cameron 9D-511-035027-121 is a 3-inch nominal size cast-iron flange-mount swing check valve designed for reliable one-way flow in industrial piping. This valve features a solid cast-iron body with flange connections rated for Class 150 service, enabling straightforward integration with standard piping flanges. As a swing-check valve, it uses a pivoting disc that opens to permit forward flow and automatically seats to resist reverse flow when flow reverses, helping protect pumps, meters, and downstream equipment from backflow-related damage. The model number identifies a specific configuration within Cameron’s Wheatley swing-check family, reflecting the long-standing Cameron/Wheatley approach to durable, serviceable check valves used in process and utility piping. With a 3-inch nominal size, it suits moderate-line applications where space and bolt patterns align with standard Class 150 flanges. When selecting this valve, verify flange compatibility and bolt pattern with existing equipment to ensure a proper fit and a leak-tight seal in service. Cameron’s swing-check valves are chosen for robust performance in demanding environments, offering dependable backflow prevention in systems such as water-handling lines and general industrial piping where one-way flow control is essential.
