Composite Butterfly Valves
(Epoxy, Vinyl Ester)

Andronaco Industries offers Nil-Cor® double-offset disc composite & epoxy coated butterfly valves that are ideal for demanding applications where tight shut-off and reduced operating torque are critical. This design allows the disc to move off the seat with a "camming" action, reducing break-away torque and seat wear. The 360° uninterrupted disc seal eliminates the leak path at the shaft hubs found on PTFE 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.

The following double-offset disc composite lined butterfly valves are available: Series 300 HD/310HD (sizes 3”-12” Wafer, 3”-12” Lug Types), Series 310HD (14”-48” Wafer, 14”-48” Lug Types).
