Installation
Install the Design V250 valve in any position, but the
recommended orientation is in a horizontal pipeline
with the shaft positioned horizontally and the ball
closing in the downward direction (see figure 1). The
actuator can be either right- or left-hand mounted as
viewed from the valve inlet for forward-flow. For
bidirectional flow, install the valve so that the highest
pressure condition will flow as shown by the flow
direction arrow on the valve body.
Dimensions are shown in figure 8.
