ATEC Segment Ball Valve Type_BL


Cavity free

The usual cavity between ball and housing in non- cavity free ball valves give cause for disturbance because residual products can crystallize, polymerize and so affect the function.

› Clean, non- false product

› No sediments of expensive products in the ball valve housing


Standard configuration in special materials

Every standard designed ball valve can be manufactured out of special materials according to customers´ request.
