Hi. I’m Ursula Sadiq, Senior Product Manager with Autodesk Plant Solutions.
In this video we are going to create block-based Valve Bodies and Actuators.
We will then assign a default actuator to a valve body, and then show how an actuator
can be set, depending on the type and size of valve.
Continuing from the previous video, we Create New Component and select the Use Custom Geometry
option. We’ll set the component category to Valves.
Notice that there are two options under Valves, Valve and ValveBody.
The ValveBody can be assigned a separate actuator, which is what we want to do here.
We’re going to set a description of Custom Gate Valve Body. The valve has 2 ports. And
for this video, I’ll create just one size. In the Sizes Tab, we’ll select the model.
We’ll open the drawing we created in the previous video.
Here, the gate valve is the block with two ports on it. We’ll set the Outside Diameter,
as required. And we’ll also set a size description.
Then we’ll move to the General Properties tab and set a long description.
And now we’ll save this item to the catalog. Next we’ll create an Actuator. We’ll create
a new component, and this time, set our category to Actuators.
We’ll set a description of Custom Actuator Hand Wheel. Set the Operator Type to Manual
and the Actuator Type to Wheel. Next we’ll set a long description, after
we create our component. Again, the Sizes tab and the port is listed
as undefined, because actuators do not connect to pipe.
We can still select a model and I’ll pick the Hand Wheel actuator that we created in
the previous video. Although the sizes list as undefined here,
you can add as many undefined sizes as you want.
You can then select a block and set a size description for each.
For this video, we are adding just one Actuator size. For the Actuator Height, we enter 6”.
And for the Width, 4”. We can now save to the catalog.
Because actuator substitution does not make much sense with just one actuator available,
we’ll create another actuator. We’ll give this one a description of Custom
Actuator Diaphragm, set Operator type to Automatic, and set Actuator type to Pneumatic.
And when we’re done with our data entry, we’ll hit Create to create this actuator.
As with the previous actuator, after we create it, we’re going to go ahead and select the
model we want, in this case the cone, and enter a long description for the size.
We’ll also make the Height and Width entries. In this case it will be a 12” by 12” actuator.
And we’ll save the actuator to the catalog. Now we can assign actuators to a valve. Here
we have our new valves and actuators in the catalog browser.
In the General Properties Tab, after picking a valve, we can click Edit Operator Assignments.
Although there are two valves in the catalog, this is the only one with an assigned Valve
Body type. The other type is not listed because you cannot
assign actuators to it. Click in the Operator drop down list, and
you can select the default operator. We’ll keep the wheel as the default.
And close the Mapping dialog. So what exactly does this mapping in the catalog
do? Well, when you now add a valve body to a spec, the default Actuator is added with
it. Let’s create a spec and use our new catalog
to take a look. In the Spec Editor tab, we’ll add this Gate
Valve to the Spec. We’ll right-click on the Valve and Edit operator assignments.
This time we’ll see that one added hand wheel operator.
This is because the pneumatic actuator is not in the spec. We’ll add the Pneumatic
actuator to the spec. Although we don’t see it on the spec sheet,
if we edit operator assignments, there it is in the drop-down list.
Another thing that you do with Valve Operator Mapping is assign a range of valve sizes to
an actuator. To show this, we’ll need more valve sizes.
We're going to load the ASME Valves Catalog, and select a Globe Valve and add it to the
spec. We’ll select a 150 pound globe valve and
add it to the spec. We can edit the operator assignments.
And here you can see the smaller sizes all share the same operator, whereas the larger
sizes have individual-sized operators. And that completes our Specs and Catalogs
series for now. For more information on the commands and procedures
covered in this video, please take a look at the Spec Editor product help.
We hope you’ll tune in for more videos where we show you how to route and edit pipe, produce
isos, and complete other plant design tasks. Thank you for watching.
