Fisher Emerson Valve Cage 2U6940X0033 CD3MN

The Fisher Emerson Valve Cage 2U6940X0033 is a precision-engineered component designed for use in Fisher control valves, such as the easy-e series globe valves. Constructed from CD3MN duplex stainless steel (ASTM A995 Grade 4A), this cage provides excellent corrosion resistance and mechanical strength, making it ideal for harsh industrial environments including oil and gas, chemical processing, and power generation applications. It facilitates precise flow control by guiding the valve plug and managing fluid dynamics within the valve body, reducing cavitation and noise while enhancing throttling performance. Key benefits include superior durability in corrosive media, high pressure and temperature tolerance, and compatibility with various trim configurations for customized flow characteristics. Compared to standard carbon steel cages, the CD3MN material offers better resistance to pitting and stress corrosion cracking, extending service life and reducing maintenance costs. Drawbacks may include higher initial cost due to premium material and potential overkill for non-corrosive applications. Based on image analysis, the unit appears to be in used but good condition, with minimal wear, a clean surface, and handwritten markings ('L61') possibly for inventory. No parent/child assets are visible. For detailed model decoding, refer to Fisher valve trim catalogs; this part number indicates a specific size and design for 1-2 inch valve bodies.
