API 6D ball valve manufacturer – Ball Valve API 6D

What is API 6D Standard?

This specification defines the requirements for the design, manufacturing, assembly, testing, and documentation of ball, check, gate, and plug valves for application in pipeline and piping systems for the petroleum and natural gas industries.

API Standard 6D, from the American Petroleum Institute, provides specifications for pipeline valves.

API 6D covers the design, manufacture, testing, and documentation for pipeline ball, check, gate, and plug valves for pressure ratings up to ASME class 2500.

VALVE SPECIFICATIONS OF API 6D

The standard specifies configurations for the following types of valves:

  • Gate valves
  • Lubricated and non-lubricated plug valves
  • Ball valves
  • Check valves
  • Full-opening valves
  • Reduced-opening valves
  • The valve ends may be flanged or welded. If fluid can become trapped in the body cavity, then valves for both gas and liquid service must have a pressure relief. Actuators may be electric, hydraulic, or pneumatic.

TESTS OF API 6D

API 6D specifies the following tests:

  • Stem backseat test
    • Pressure at 1.1 times valve rating for 2 to 5 minutes depending on valve size
    • No visible leakage
  • Hydrostatic shell test
    • Pressure at 1.5 times valve rating for 2 to 30 minutes depending on valve size
    • No visible leakage
  • Hydrostatic seat test
    • Pressure at 1.1 times valve rating for 2 to 5 minutes depending on valve size
    • Soft-seated valves: No visible leakage
    • Metal-seated valves: Leakage not more than two times ISO 5208 Rate D

ZECO Valve supplies API 6D Valve, Pipeline Valve including Ball Valve, Gate valve, Globe valve, Check valve, and Butterfly valve.
