<p>PURPOSE: To facilitate desired functional setting by dividing a housing hole into separate longitudinal sections, forming a cross hole on each section to movably-dispose a sealing disc, inserting a cross channel connected to a pressure conduit, a control conduit, and an exhaust tube into the housing hole, thereby setting a prescribed function. CONSTITUTION: A casing hole 29 is divided into two separate longitudinal sections 29a, 29b with cross holes 30 respectively. Through-holes are formed on the ports 31 of the respective cross holes 30 so as to dispose sealing discs 32 which are rotatable or slidable in the cross direction. Cross channels 36 connected to a pressure conduit P, control conduits Z, Y, and exhaust tubes R or S are inserted into the two longitudinal sections 29a, 29b from a longitudinal side surface 2. The respective cross channels 36 are set in an opening or closing function by an integral bottom sealing member 4. The casing hole 29 and the sealing discs 32 are combined, thus it is possible to attain a plurality of valve functions.</p> |
