BALLOMAX Standard Trunnion Mounted & API 6D Ball Valves

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 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).
