Key Standards by Application

Pipeline Valves:

• API SPEC 6D: The foundational specification for ball, check, gate, and plug valves in pipeline systems.

Pressure Relief Valves:

• API 526: Purchase specification for flanged steel pressure relief valves.
• API 527: Methods to test the seat tightness of these valves.
• API 520-1: Guidelines for sizing and selection.

Inspection, Testing, and Fire Safety:

• API 598: The primary standard for valve inspection and pressure testing.
• API 607 & API 6FA/6FC: Standards for fire testing soft-seated quarter-turn valves and other valve types, respectively.

Specific Valve Types:

• Check Valves: ANSI/API STD 594
• Plug Valves: ANSI/API 599
• Gate Valves: ANSI/API 600 (Bolted Bonnet), API 602 (Compact), ANSI/API 603 (Corrosion-Resistant)
• Butterfly Valves: API 609

Gas Lift Valves:

• API 11V6 & ANSI/API RP 11V7: Cover design, repair, testing, and setting of gas lift systems and valves.
