A valve has two objects that need to be configured. The first is called "Active" and is sort of Open/Close. It needs a listen and set address. The Datapoint Type is 1.001

The second object is called "In Use" which means there is actually a flow (of water). If you do not have anything that represents this, use the listen address of the "Active" above. The Datapoint Type is 1.002

You may want to change "Valve Type" parameter. Here are the options in the image below.

This option make device appearance like icons change on Home app.
