<p>Diverter valve, controlling the flow of viscous fluids through one or the other of a pair of filters and having no isolated flow areas subject to stagnation constructed of a slide plate (54) sandwiched between a manifold block (50) and a backing plate (52). The slide plate defines a passageway which mates with ports provided in a sealing surface of the manifold block so that a continuous flow path is provided between inlet and outlet of the diverter valve. Sealing pressure is maintained between the slide plate and the manifold block by a plurality of tie bolts urging the slide plate into contact with the manifold block.</p> |
