Abstract
Abstract A valve assembly, particularly useful between flanges, which utilizes a housing unit and a separate valve unit. The housing unit provides a supporting housing adapted to be supported between the flanges and to include a valve operator and a first valve stem. The valve unit is sized to be inserted in the housing unit and includes the valve member, seats, and at least one additional valve stem. The valve stem carried by the housing unit is insertable lengthwise into connection with the valve stem of the valve unit. In an assembled position, the valve unit is sealed against the flanges and prevents the housing unit from being contacted by fluid controlled by the valve.
