Rubber Lined Eccentric Butterfly Valves
Description
Hugo Rubber Lined Eccentric Butterfly Valve features a fully-lined body and a double-offset disc design, PTFE and Elastomer Lining, high performance eccentric design makes the butterfly valve of choice for applications with high pressure and exposure to corrosive fluids.
The 360° uninterrupted disc seal eliminates the leak path at the shaft hubs found on and rubber-lined competitors valves. a super-strong 17-4 ph shaft encapsulated with graphite reinforced vinyl ester resin eliminates corrosion and assures long trouble-free operation
