Valve Components

Precision investment cast valve bodies, bonnets, seats, and stems for oil & gas, chemical processing, and industrial applications. ANSI pressure ratings up to Class 2500.

Valve body - precision investment casting

Complex Internal Geometry

Investment casting creates flow passages and sealing surfaces impossible to machine, reducing assembly and leak paths.

Pressure-Rated Castings

Materials and processes qualified for ANSI pressure classes up to 2500, with full material traceability and test reports.

High-Temperature Service

Alloy selections for service temperatures from cryogenic to 600°C+, including special grades for severe applications.
