  • Publication number: 20150292633
    Abstract: An inert linear shear valve is presented for fluidly coupling at least two flow passages. The linear shear valve includes an actuation device (12) that moves a sliding plate (24) to a position where the at least two flow passage (16,18,20) are fluidly coupled. The sliding plate (24) is biased towards a manifold (14) containing the flow passages (16,18,20) by at least one resilient member (28,30) housed in a carrier (22). The sliding plate (24) has a minimal contact area with the manifold to minimize wear of the sliding plate 24) and the manifold (14).
