Abstract

An isolation valve assembly comprises a valve body defining a first fluid port and a second fluid port opposing the first fluid port and at least one drain port disposed between the first fluid port and the second fluid port, an isolation valve disposed within the valve body and a handle operatively coupled to the isolation valve. The handle is movable to cause corresponding movement of the isolation valve between a first normal position where the isolation valve fluidly couples the first fluid port and the second fluid port, and a second drain position where the isolation valve fluidly couples the first fluid port and the at least one drain port and isolates the second fluid port.
