    • A slide valve comprises a valve body (1) having valve ports (6, 7, 8) and a spool (4) mounted within and slidable relative to a cylinder liner (2) in the valve body for controlling the opening, interconnection and closing of the valve ports. The spool carries a valve block (12) forming a sealing member which is floatingly located in a recess (11) in the spool, and which includes one or more galleries (15) to provide interconnection between two or more of the ports in one or more defined positions of the spool. The sealing member (12) also has at least one sealing surface (14) for sealing off one or more of the ports in one or more defined positions of the spool (4), the sealing member being urged into its sealing position by means of fluid pressure applied through at least one of the ports.
