MSS SP-67 Standard EPDM Seated Center lined Butterfly Valve
MSS SP-67 Standard EPDM Seated Center lined Butterfly Valve
Overview
The wafer type centerline butterfly valves
are used in on-off block applications, with a simple disk in line with the
center of the valve body. Generally, wafer type centerline butterfly valves are
made from cast iron or another inexpensive metal and are lined with rubber or a
polymer. The wafer body, sometimes called the flangeless body, is a flat body
that has a minimal face-to-face, which is equal to twice the required wall
thickness plus the width of the packing box.
