Installation
It is recommended that the valve drive shaft be
mounted in a horizontal position. Operating
conditions may require specific valve/actuator fail
action, styles, positions and flow direction. Valves with
NOVEX seal rings require mounting in the reverse flow
direction. Refer to figure 4. Large valve/actuator
assemblies may r equire additional support because of
the combined weight.
Fail Action: For actuators with spring returns, spring
fail action is available for: fail-to-open or fail-to-close
valveaction.Thevalveaction is field rev ersible.
For assistance in selecting the valve/actuator
mounting suited to your application, consult your
Emerson Process Management sales office.
Dimensions for wafer-style and single-flanged valves
are shown in figure 6.
