ABSTRACT:
A valve that is particularly useful in biological fluid handling systems includes a body member that has a firm and stable support surface and a flexible sheet member that has a surface for conforming and mating engagement with the surface of the valve body member. A land portion in the surface of one of the valve members separates two fluid flow channels in that member. An actuator is arranged to flex the sheet member between a first position in which the surface of the sheet member is in mating and sealing engagement with the surface of the body member to sealing block flow between the two channels, and a second position in which the sheet surface is spaced from the first position to allow fluid flow across the land surface between the two flow channels.
