  • Patent number: 4615505
    Abstract: A fluid valve system (10) is provided to control fluid flow passing from a conduit passage (12). The valve system (10) includes a movable closure (20) which is reversibly displaceable in a transverse direction (22) passing in a direction substantially normal to the fluid flow passing in a longitudinal direction (14). The movable closure (20) is insertable within the conduit passage (12) in order to block or cut off the fluid flow passing through aligned conduits (16 and 18). The valve system (10) includes a pair of resilient sealing mechanisms (34) which provide for substantially planar second sealing base members (46) for resiliently contacting opposing surfaces (48 and 50) of movable closure (20). Additionally, there is provided a biasing mechanism (56) for resiliently biasing the second sealing base members (46) into contiguous contact with surfaces (48 and 50) of movable closure (20) over an extended area.
