One of the most important factors in the expansion of the oil and gas industry has been the development of standards in the design, engineering, and manufacturing of parts and components. This is not only important for environmental safety, but it is also critical to prevent accidents and possible hazards during the construction, testing, and use of oil and gas lines around the world.
The API 6D designation, sometimes called the API Spec 6D specification, details the design, manufacturing, testing, and required documentation for all pipeline valves, including ball, plug, gate, and check valve styles. This specification covers valves used in pipelines. It also outlines all requirements of valves used in these systems to meet the standards set forth by the American Petroleum Institute.
What is an Expanding Gate Valve?
An API 6D expanding gate valve is designed to meet the API 6D specifications for oil and gas industry use. As a gate valve, these components serve to stop, open, or throttle the flow of oil or gas through the valve based on the specific requirements for the process.
The API 6D expanding gate valve is designed in two parts or two units. These units include the actual gate component as well as the outer segment. This design allows for an extremely tight and complete seal while expanding against the seal or seating areas when in the closed or open position. This design eliminates any issues with the seal in high temperature applications or when there are changes in the pressure in the line.
The API 6D expanding gate valve is also very resistant to any loss of seal due to vibration. Different designs can be used with actuators or operated manually.
