    摘要： A gasket 4 to be interposed between a valve mounting face 2a of a manifold base 2 and a joining face 3a on a casing of a change-over valve 3 is provided with ridges 35 at least on one side thereof. On the other hand, grooves 12 or 20 are substantially complementarily formed on the valve mounting face 2a of the base 2 or on the joining face 3a of the valve casing, so that the gasket 4 is securely clamped between the valve mounting face 2a and the joining face 3a not only at the ridges 35 but also at flat seal surfaces 4a on the opposite sides of the ridges 35.

    摘要： Piston boxes are attached to both ends of a valve body of a main valve segment having multiple ports and an axial valve port. Projections extending toward the valve port are provided in piston chambers provided in the piston boxes. The pistons have pressing tips to push the valve member and recesses and adapted to accommodate the sliding projections. The relative motion between the projections and recesses guide the slide of the pistons.

    摘要： A two-port valve includes a valve part configured to open and close a valve seat in a liquid flow path connecting a first port and a second port by a valve member and a pilot-type valve driving mechanism to open and close the valve member through a rod. The rod passes through an insertion hole of a plate facing on the liquid flow path in a sealed state. The valve member is provided to the tip part of the rod and also a cap which abuts against the periphery of the insertion hole of the plate when the valve member opens the valve seat and prevents intrusion of foreign material in the liquid into the insertion hole is provided to the rod.

    摘要： In a switching valve containing a valve member for opening and closing a valve seat and a piston for driving the valve member by the action of a pilot fluid pressure inside a valve housing, a magnet for positional detection is attached to the piston, two sensor attachment grooves extending in the direction of the axial line L of the switching valve and having different groove lengths in accordance with the operational position are formed in parallel on the side face of the valve housing, and magnetic sensors are attached at locations on the side of the innermost end wall in the attachment grooves.
