It should be noted that the direction of flow and differential pressure, do not always coincide.
Special care should be taken to maintain the correct distance between the flanges and to
ensure that they are parallel to the valve body. Incorrect alignment of the valve can cause
deformations, which can lead to difficulties in operation.
The following table gives the maximum torque values for the valve fixing bolts. Also shown is
the maximum depth (T) allowed for the tapped blind boltholes drilled into the valve body.
