Stacey Line Blind Valve

The modern line blind valve "Stacey" ensures the total isolation of the downstream flow within a pipeline.


It is an essential addition to the SchuF Fetterolf Line Blind product range as it is ideal for certain types of applications where the line blind must be both - large and have a high pressure rating.
