<p>Embodiments described herein provide a valve construction. One embodiment comprises a first valve (12) and a second valve (14). A first fluid conveying conduit (16) fluidly conveying a first fluid is fluidly connected with the first valve (12). A second fluid conveying conduit (18) fluidly conveying a second fluid is fluidly connected with the second valve. A third fluid conveying conduit (22) is fluidly connected with the first valve (12) and the second valve (14). The first valve (12) is movable between a first position where first fluid flows between the first fluid conveying conduit and the third fluid conveying conduit, and a second position where first fluid does not flow between the first fluid conveying conduit and the third fluid conveying conduit. The second valve (14) is movable between a first position where the second fluid flows between the second fluid conveying conduit and the third fluid conveying conduit, and a second position where the second fluid does not flow between the second fluid conveying conduit and the third fluid conveying conduit.</p> |
