Modeling a valve actuator with a support requires a different modeling approach. Instead of specifying "Yes" to Operator/Actuator in the Define>Components>Valve dialogue and then entering weight and offsets, instead leave the Operator/Actuator field "No". Instead we We will use Draw joint to draw a joint/point offset from the valve to the CG of the actuator/operator, connect the joint to the valve using a body constraint, assign a -Z downward point load on that joint for the actuator weight, then draw, insert, or assign a pipe support to the newly drawn joint. If you're connecting to the valve midpoint, you will need to draw a joint at the valve midpoint.
If static acceleration or dynamic load cases are defined, the user will also need to go to Define>Mass Sources to specify the load pattern used for the actuator weight to be included in the mass source. Do not add DEAD load pattern if the "Element self mass" option is checkboxed, otherwise you will double count selfweight mass. In this example we defined a new load pattern called ACTUATOR WT which was added to the mass source as shown below.
