Mode of operation

Flanged gate valves are used to completely open or close the entire cross-sectional area of flow. They are
not suitable for the precise regulation of the quantity of fluid flowing through. In the fully opened state they
provide virtually no flow resistance.
Globe valves are used for the controlled opening or closing of flow apertures or pipelines. They regulate
the flow of fluids in fluid and gas installations.
These valves are preferably used for media such as transformer oil at max. 6 bar and max. 120 °C and
non-flammable, non-toxic fluids.
