UGRESHA Butterfly valves
Cast iron flanged butterfly valves UGRESHA, DN 300 – DN 1400, PN 10, 16.
The lower and upper axle shafts have closed bronze bearing bushings, which provide double sealing of the axles in both directions and protect the axle shafts from the working medium. The axle shaft construction is less vulnerable to corrosion, as a result, the service life of the butterfly valve increases.
