FLANGED AND BUTT-WELD ENDS - KNIFE GATE CLASS 150 Sizes 2''-12''
Cast stainless steel body and investment cast yoke. In fabricated valves, leakage of corrosive medium due to neglected maintenance on the packing, or line pressure surges, causes corrosion and failure of most carbon steel or cast iron components. An all stainless steel valve offers better corrosion resistance than cast iron lined valves. The total cost of ownership becomes more attractive than the initial savings. |
