Description
Trunnion Mounted Ball Valve
Compared to floating ball valves, trunnion mounted ball valves feature an additional support for the ball from the bottom.
This support is called trunnion. The trunnion absorbs any pressure from the flow and keeps the ball constantly in the same position.
The sealing is provided by spring-loaded seats. This design reduces the stress on the ball and seats of the valve and makes the sealing performance more stable and consistent, independently from the flow pressure.
Trunnion mounted ball valves are ideal in high-pressure services, while allowing for low operating torque requirements.
API 6D and its Monogram
API 6D is the globally recognized specification that defines the requirements for the design, manufacturing, assembly, testing, and documentation of ball valves and other types of valves for application in pipeline and piping systems for the petroleum and natural gas industries.
The API Monogram Program identifies the finest organizations in the world that have demonstrated their ability to manufacture new equipment that conforms to API product specifications.
The API approval also requires a Quality Management System that is compliant with API Spec Q1. A thorough audit by API is periodically required to maintain the Monogram.
We are pleased to announce that for decades BROEN has maintained the API 6D Monogram (6D-0378).
