ASTM A494 M35-1 ball valve

Your specified valve is technically plausible, but several details must be confirmed before approving it pentru procurement.

1. Material şi standards verification

Item	Verification
Corp 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 în the order
Nominal size	DN50, approximately NPS 2
Pressure designation	PN16, nominally 16 bar
End connection	Flanged; flange standard şi facing must be confirmed

ASTM identifies A494/A494M as the specification pentru nickel şi nickel-alloy castings intended pentru corrosion-resistant service. M35-1 composition data are also published în foundry technical references.

2. Critical points to resolve

Pressure rating: PN16 alone does not prove that the completed valve is suitable pentru 16 bar at your operating temperature. Obtain the manufacturer’s pressure-temperature rating.
Flange compatibility: Confirm whether the flanges must comply with EN 1092-1 PN16, another standard, or A project-specific requirement. Check dimensions, facing, şi drilling.
Wetted materials: Specify the body, ball, stem, şi other pressure-containing or wetted parts separately. Do not assume all components are M35-1.
Scaun şi packing: Select PTFE, reinforced PTFE, or another suitable material according to fluid compatibility, temperature, şi leakage requirements.
Testare şi documentation: Require pressure-test reports, material certificates, şi traceability appropriate to the project.

Important: Coroziune resistance is medium-specific. Before approving M35-1, confirm the actual fluid, concentration, temperature, şi any contaminants. Material selection should be based on those conditions rather than the alloy name alone.
