Valve Body
Application: EMD 645 and 710 cylinder test valve assemblies
Part of our Cylinder test valve product line
The Valve Body is identified by EMD Part No. 8048883. EMD parts references specifically identify 8048883 as the Body of the Cylinder Test Valve and list it as a component of the cylinder test valve assembly. The part is used in EMD 645 and 710 cylinder test-valve applications. No reliable DLW cross-reference was identified in the sources reviewed, so the DLW number should remain unassigned.
How This Part Works
The Valve Body is the main body component of the EMD cylinder test valve assembly. It provides the body and associated passages or interfaces for the needle valve, packing arrangement, and sealing components within the assembly.
Signs It's Time to Replace
- Visible body damage: cracks, deformation, or other physical damage should be assessed
- Thread damage: deterioration of threaded interfaces can affect proper assembly
- Valve-seat or internal-surface wear: abnormal deterioration of relevant internal surfaces should be investigated
- Corrosion: significant corrosion or material deterioration should be evaluated
- Leakage: leakage from the valve body or its connections can indicate deterioration of the body, seals, or associated components
Apex focuses on EMD engine components and cylinder test-valve parts for EMD applications. The Valve Body is identified by the specific EMD Part No. 8048883 and its EMD 645 and 710 cylinder test-valve application. This part-number-based identification helps customers distinguish the cylinder test valve body from the needle valve, packing nut, and seal used in the same assembly.
