Recently, a client mentioned that they couldn’t locate threaded plug valves in the catalogs. Today’s post will show how to create a custom valve from scratch. Today we will use a Tufline Sleeved Plug valve: http://www.cranechempharma.com/chempharma/products/valves/xomox-sleeved-plug-valves/screwed-end-sleeved-plug-valves&brandid=6FDB472B-D7F3-EA31-D0E970EBF58FA22A

Below is an overview of the process we will use.
- Locate the data sheet.
- Select the sizes to create, type of valve, and the drawing script to use.
- Add General property data.
- Add size property data.
- Add modeling dimensions.
In the catalog editor tab, click the Create New Component button.
The data sheet includes size for 1/2” to 2” so we will create all of those sizes. Also, choose the Valves Component category, the ValveBody piping component, set the end type, and give a short description. Choosing the ValveBody piping component allows us to define the valve separately from the actuator information which is the way most of the valves are built. For the graphics, there is a plug valve with female threaded ends already, so we will use that script. The script chosen was CPVI010000_OFOF which is important because it lets us define the length of the threaded hub.
The critical information is the Part Family Long Description, and then the information on each of the sizes. Here’s the critical information I used. In addition, fill out the alignment, detail, body type, symbol type, and skey to make the valve conform to similar valves and show up correctly on the iso.
The for each size, enter the matching pipe od, a long description size, and the appropriate dimensions. Make sure to check All Ports have the same properties.
Be sure to check out our library of helpful charts:http://www.pdoteam.com/resources/piping-component-library/
For the engagement lengths, use the nipple engagements chart for Plant 3d:Checkout (0 downloads)
The left side contains data properties for the component:
For D1 I used the OD of the pipe, for H1, I used the C value from our data sheet, L is the length from the data sheet minus 2 times the engagement, I1=.5 is the nipple engagement from our standard Plant 3D nipple engagements. The length of the threaded hub is L1=0.55.
Once we have those items, filled in, Plant has the information required to create the part.
