The valve gate range ECOLINE GT 40 in butt weld end design has been developed for non-corrosive media such as water, steam, gas and oil. A version with butt weld ends is now available alongside the model with flanged ends. The new butt weld end variant can be supplied in nominal diameters from DN 50 to DN 600 and in pressure classes up to PN 40.

The gate valves come with connection branch extensions made of high-quality forged steel. The valve range has been specially developed for industrial applications and its design has focused on ensuring absolutely reliable sealing to atmosphere.
KSB has achieved this by employing a fully confined bonnet gasket in graphite together with graphite packing end rings. This creates a barrier preventing the sealing material from creeping. A screwed back seat fitted as standard reduces the load on the stem seal when the flexible wedge is fully open and, in the event of a malfunction, ensures blow-out protection for the non-rotating stem with its burnished shank.
