Bellows Seal Gate Valve
Bellows seal gate valve is suited to be applied in industrial fields to control water, oil or steam pipeline, with a nominal pressure of PN1.6~4.0MPa and a temperature of -29~350℃.
Salient Features
a. Our bellows seal valve features reasonable structure, reliable sealing, aesthetic appearance, and excellent performance
b. Cobalt-based hard alloy is welded on the sealing layer with surfacing technique, contributing to good corrosion-resistance and wear resistance
c. Quenching and intruding treatment is given for the valve stem for resistance to corrosion and abrasion
d. The double sealing technique provides powerful guarantee for the valve's performance
e. Position of the valve stem is shown intuitively
f. The valve material, flange, and welding dimension can be adjusted according to customers' actual needs
