<p>An improved axial flow valve construction includes a valve body (100) and a pair of identical and interchangeable end closure members (126). The valve body includes a cylindrical opening (106) defining the interior of the valve body, a first plurality of open channels (108) extending from a first end of the valve to the valve body interior and a second plurality of open channels (110) extending from the valve body interior to the second end of the valve body. A flexible tubular sleeve (122) is located within the cylindrical opening. The valve further includes means for providing external communication to the first plurality of open channels and means for providing external communication to the second plurality of open channels. Each of the end closure members includes means for providing a fluid path from either the fluid inlet to the first plurality of open channels or the fluid outlet to the second plurality of open channels, depending upon the orientation of the valve and the end of the valve covered by the end closure member, as well as means for providing external fluid communication to the interior of the sleeve.</p> |
