Forged Steel Valve
API 602 300LB A105 Forged Steel Extended End SW Gate Valve
Summary
300LB A105 Forged Steel Extended End SW Gate Valve is designed for isolation in oil and gas, power generation and industrial process piping under Forged steel gate valve. gate construction is aimed at on/off isolation with low pressure drop when fully open. Carbon-steel pressure parts suit general hydrocarbon and utility service when corrosion allowance and coating are defined on the data sheet. 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.

Product FAQ
Engineering answers
What size and pressure range is the 300LB A105 Forged Steel Extended End SW Gate Valve supplied in?
The catalogue series is DN8-DN50 (1/4"-2"), Class 300 / PN50. A single NPS/class line in the notes is a typical working-size snapshot for drawing discussion, not the series limit. Confirm NPS, class, bore and trim against the approved data sheet.
Which documentation is included in a standard EPC MDR package?
When specified: approved GA drawing, EN 10204 3.1 material certificates, hydrostatic/pneumatic test records to the applicable test standard, NDE reports required by the ITP, coating records if painted, and the ITP release note. CAD/STEP models and bilingual datasheets are issued after size, class and trim are frozen — they are not generic public downloads.
Which design and test standards apply to the 300LB A105 Forged Steel Extended End SW Gate Valve?
Design reference: API 602, ASME B16.34. Face-to-face: ASME B16.10 / ASME B16.11. Pressure test / inspection: API 598 / project ITP. NACE, fire-safe or fugitive-emission clauses are quoted only when the purchase specification requires them.
