This document provides the necessary exploded view diagrams and parts identification for the Danfoss 027F3371 overhaul kit, specifically designed for PM size 25 valves. Before beginning maintenance, identify whether your valve is a PM1 or PM3 model, as assembly requirements differ.
Product Overview
The guide features detailed exploded view diagrams for both PM1 and PM3 valve configurations. These diagrams illustrate the correct placement of components 1 through 20. Ensure you reference the correct diagram for your specific valve model to avoid incorrect assembly.
Parts List and Specifications
The kit contains various components made of either Aluminum (Alu.) or Fibre. Each part is numbered and corresponds to the exploded view diagrams. Please note the following:
- Material Types: Components are specified as either Aluminum or Fibre. Ensure the correct material is used for the corresponding seal or gasket location.
- Unused Parts: Some spare parts included in the package are not used for PM1 or PM3 configurations. Do not be alarmed if you have leftover parts after completing the assembly for these specific models.
- Dimensions: The guide provides specific dimensions (e.g., diameter in mm and inches) for each part to assist in identification.
Maintenance and Assembly
When performing an overhaul, follow the exploded view diagram carefully. Ensure the valve is fully depressurized and isolated from the system before attempting any disassembly or part replacement. Verify that all seals and components are seated correctly according to the diagram before re-pressurizing the system.
