KOSO 210C Concentric Segmental Ball Valves (FLOWMAX C/Wafer)

KOSO 210C Concentric Segmental Ball Valves (FLOW MAX C/Wafer) are concentric segmental ball valves for modulating application. KOSO 210C Concentric Segmental Ball Valves (FLOW MAX C/Wafer) V-notch cut at disc makes rangeability larger and creates the shearing effect by disc and seal ring. KOSO 210C Concentric Segmental Ball Valves (FLOW MAX C/Wafer) suitable to large rangeability service and/or control of fluids with fiber and/or slurry.

Product Features

KOSO 210C Concentric Segmental Ball Valves (FLOW MAX C/Wafer) are concentric segmental ball valves for modulating application. KOSO 210C Concentric Segmental Ball Valves (FLOW MAX C/Wafer) V-notch cut at disc makes rangeability larger and creates the shearing effect by disc and seal ring. KOSO 210C Concentric Segmental Ball Valves (FLOW MAX C/Wafer) suitable to large rangeability service and/or control of fluids with fiber and/or slurry.

KOSO 210C Concentric Segmental Ball Valves (FLOW MAX C/Wafer) have the lowest flow resistance (actually 0). Because it will not get stuck when working (when there is no lubricant), it can be reliably used in corrosive media and low boiling point liquids. It can be completely sealed in a larger pressure and temperature range. Fast opening and closing can be realized, and the opening and closing time of some structures is only 0.05~0.1s to ensure that it can be used in the automation system of the test bench. When opening and closing the valve quickly, there is no shock in operation. The spherical closure can be automatically positioned on the boundary position.

The working medium is reliably sealed on both sides. When fully open and fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, so the medium passing through the valve at high speed will not cause the erosion of the sealing surface. Compact structure and lightweight, it can be considered as the most reasonable valve structure for a cryogenic medium system. The valve body is symmetrical, especially the welded valve body structure, which can well withstand the stress from the pipeline. The closing piece can withstand the high-pressure difference when it is closed. The ball valve with the fully welded body can be directly buried in the ground so that the internal parts of the valve are not corroded, and the maximum service life can reach 30 years. It is the most ideal valve for oil and natural gas pipelines.
