VALVE CONSTRUCTION
The standard Series 2000 Butterfly Valve is
constructed of rugged cast iron with a stainless steel
shaft and resilient disc edge. See the specific
Materials List submitted for the order if other than
standard cast iron construction. The details of
construction are illustrated in Figure 2.
The body (1) is available with flanged or mechanical
joint ends for connection to the pipeline. The body is
equipped with a stainless steel seat (2). The 1/4
turn disc (3) is guided by a stainless steel shaft (4)
which rotates in non-metallic bearings (5) fixed in the
body. Leak-tight closure is made when the resilient
seat (6) is rotated into the stainless steel seat on the
"SEAT END" of the body.
