• Marking: MSS SP-25

6. Remarks

1. Material Characteristics: ASTM A351 CF3M is the cast equivalent of UNS S31603 (316L) . It features ultra-low carbon content, providing excellent resistance to intergranular corrosion after welding and in chloride environments.
2. Metal Seated Feature: This valve features a Metal-to-Metal Hard Seal, making it suitable for high-temperature applications. The allowable leakage rate typically conforms to ISO 5208 Rate D(or API 598) for metal seats (a minute leakage is permissible; zero leakage is generally not guaranteed for standard metal seats).
3. Flow Direction: A permanent flow directional arrow is cast or marked on the valve body. Installation must align with the pipeline flow direction.
4. Installation Guidance: Best installed in horizontal pipelines with the shaft in a vertical position. For vertical installations, flow must be in the upward direction to allow the discs to open properly.
