Floating Ball Valve

UTMOST, a floating ball valve manufacturer, offers different floating ball valve types at a good float ball price. The floating ball valve has a simple structure and good sealing performance, but the load of the working medium on the sphere is all transmitted to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the sphere medium. When subjected to higher pressure impact, the sphere may shift. This valves and controls structure is generally used for medium and low-pressure ball valve and float.

Floating Ball Valve Application of Norms

  • Flange dimensions to ANSI B 16.5

  • Face to face dimensions to ANSI B 16.10

  • Floating ball valve design and Manufacture in accordance with API 6D

  • Valve tested to API 598
