    摘要： In a high pressure needle valve, a central valve stem extends through a conventional operating sleeve for effecting axial shiftig of a valve head on the inner end of the stem. The outer end of the stem is plain to receive a push-fitted retainer, and a disc or flange spring compressed to approximately 60% is arranged between the retainer and the outer end face of the operating sleeve.

    摘要： A female screw member includes a female screw part with a female screw, and a projection part projecting in the direction of a center shaft of the female screw and having a working face in the rotating direction centering on the center shaft. The female screw part and projection part are integrally molded with a resin. The projection part has a spiral inclination face spirally inclining by one round from the working face centering on the center shaft of the female screw. The height H of the working face is equal to or smaller than a pitch P of the female screw. Using the projection part as a fully opening fixing stopper, a motor operated valve includes a valve main body having a valve seat, the female screw member attached to the valve main body, a motor having a rotator and stator, and a valve shaft. The valve shaft is screwed to a female screw of the female screw member, and is rotated and driven by the rotor, and has a fully opening movable stopper capable of contacting the fully opening fixing stopper.

    摘要： A valve, includes a housing formed with a valve seat and having an inlet port and an outlet port; and a shut-off member positioned in a passageway between the inlet port and outlet port and so adjustable as to enable a separation of the inlet port and the outlet port from one another when seated on the valve seat, wherein the valve seat exhibits a seat surface which is so inclined in circumferential direction that intersections of diametrically opposed tangents constructed on the seat surface of the valve seat define an area.

    摘要： A pressure reducing valve that is particularly adapted for use with steam at high pressures and temperatures. The valve embodies a main valve seat member that is provided with a valve seat and flow control means disposed downstream of the valve seat to prevent development of zones of excessive velocity of flow through the valve seat and to prevent excessive noise in operation. The position of the main valve spool that controls flow through the main valve seat is controlled by a piston operating in a cylinder and the supply of fluid under pressure to the cylinder is controlled by a pilot valve assembly. The main valve seat member and the main valve spool and the pilot valve assembly can readily be removed from and replaced in the housing of the valve without breaking the connections between the housing and external fluid conduits.
