VALVE CONSTRUCTION
The standard Series 4000 Ball Valve is constructed of
rugged cast iron with stainless steel shafts and resilient
seat. 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 Class 150# or Class
300# flanged ends for connection to the pipeline. The
body is equipped with a stainless steel seat (2). The
1/4 turn ball (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) located on the ball. If the valve is labeled as a
“Single” seat valve, the seat will be on the right end
and this is the end that is installed toward the pump.
