Abstract
A selector valve (102) having at least first and second ports (108 and 110) is provided. The selector valve includes a closure element (120) selectively displaceable between a first position, wherein the closure element (120) sealingly engages the first port (108), and a second position, wherein the closure element (120) sealingly engages the second port (110). The selector valve (102) further includes a cam assembly that is configured to bias the closure element (120) into at least the first or second position in a manner such that the closure element (120) does not come into substantial contact with the first or second port (108 or 110) when being moved into the first or second position.
