There is no such field type as "Open/Close". There are text, yes/no, date, currency,... field types. If a field value is "Open" then I expect the field type is text. To count the records in a report where the [ValveStatus] = "Open", use a text box in a group or report footer bound to the expression:
=Sum(Abs([ValveStatus]="Open"))
