Forged Steel Valve
API 602 4" Class 300 Forged Stainless Steel Globe Valve
Summary
4" Class 300 Forged Stainless Steel Globe Valve is designed for throttling and isolation in power, refining and process piping under Forged steel globe valve. globe geometry supports throttling and tight isolation when trim and Cv are matched to the duty. Typical duties include oil & gas, power generation, chemical processing. Confirm end connection, trim, actuation and inspection scope against the approved project data sheet.
Features
Product features
- Forged-body construction
- High-pressure service options
- Project-specific end and trim configuration
Advantages
Selection advantages
- Select NPS and pressure class inside the published catalogue envelope; freeze the working size on the data sheet before GA release.
- Design basis and face-to-face follow the standards shown in the technical grid; do not assume a single standard covers every option.
