ASTM A494 M35-1 ball valve
Your specified valve is technically plausible, but several details must be confirmed antes approving it para procurement.
1. Material y standards verification
|
Item |
Verification |
|---|---|
|
Cuerpo material |
ASTM A494/A494M Grade M35-1 — nickel-copper alloy casting |
|
Alloy family |
Ni-Cu, commonly associated with Monel-type alloys |
|
Typical chemistry |
Nickel balance; copper 26–33%; iron max. 3.5%; carbon max. 0.35% |
|
Material standard |
ASTM A494/A494M, with the applicable edition specified in the order |
|
Nominal size |
DN50, approximately NPS 2 |
|
Presión designation |
PN16, nominally 16 bar |
|
End connection |
Flanged; flange standard y facing must be confirmed |
ASTM identifies A494/A494M as the specification para nickel y nickel-alloy castings intended para corrosion-resistant service. M35-1 composition data are also published in foundry technical references.
2. Critical points to resolve
-
Presión rating: PN16 alone does not prove that the completed valve is suitable para 16 bar at your operating temperature. Obtain the manufacturer’s pressure-temperature rating.
-
Flange compatibility: Confirm whether the flanges must comply with ES 1092-1 PN16, another standard, o a project-specific requirement. Check dimensions, facing, y drilling.
-
Wetted materials: Specify the body, ball, stem, y other pressure-containing o wetted parts separately. Do not assume all components are M35-1.
-
Asiento y packing: Select PTFE, reinforced PTFE, o another suitable material according to fluid compatibility, temperature, y leakage requirements.
-
Pruebas y documentation: Require pressure-test reports, material certificates, y traceability appropriate to the project.
Important: Corrosión resistance is medium-specific. Before approving M35-1, confirm the actual fluid, concentration, temperature, y any contaminants. Material selection should be based on those conditions rather than the alloy name alone.
