Abstract
A drain valve includes a valve body that defines an inlet seat and a first outlet seat downstream of the inlet seat. A first member has a first position in sealing engagement with the first outlet seat and a second position separated from the first outlet seat. A second member has a first location in sealing engagement with the inlet seat. A sensor downstream of the inlet seat generates a signal reflective of a pressure downstream of the inlet seat. A method for operating a drain valve includes moving a first element in a valve body to allow fluid flow through the valve body, moving a second element in the valve body to allow fluid flow through the valve body, and sensing a pressure in the valve body.
