    Abstract: This invention relates to a ball valve having a valve body with a bonnet bore communicating with a through fluid bore. A valve seat in the valve body surrounds the fluid bore axis. A bonnet with a stem bore extending therethrough is received in the bonnet bore. An operating stem is journalled for rotation in the stem bore. A ball is connected to the stem and located in the fluid bore. The ball has a through passageway. Rotation of the stem causes the ball to rotate eccentrically between an open position at which the ball is spaced from the valve seat with its through passageway aligned with the fluid bore, and a closed position at which the ball blocks the fluid bore by being wedged into sealing engagement with the valve seat. The ball is externally contoured to provide both a clearance from the valve body to accommodate its eccentric rotation, and a stop which is engageable with the valve body to positively locate the ball in its open position. The invention also includes the aforesaid ball valve assembled in combination with an actuator having a linearly reciprocating piston mechanically connected to the valve stem by means of a rack and pinion. Linear motion of the piston is limited in one direction by the sealing engagement of the ball with the valve seat, and in the opposite direction by the engagement of the ball stop with the valve body.

    Abstract: This relates to a ball valve of the top entry non-spherical type. A soft metal coating is deposited on that portion of the seat ring which contacts the valve member or ball. The ball and seat assembly is inserted into a valve chamber such that the seat rings are in an unstressed condition. After insertion, the ball is rotated 90.degree. causing the ball to engage the soft metal coating, thereby crushing the soft metal to form a tight seal with the ball. In this manner, the lapping process, generally required when metal seats are employed, is eliminated. Further, the seats may be replaced without replacing the ball.

    Abstract: The invention relates to cocks having a rotating valve and sliding seats. A cock according to the invention comprises a body equipped with fluid-passage ducts, a rotating valve, sliding seats in each duct and, to the rear of each seat, an annular space within which there slides an annular piston which is pushed towards the seat by a pressurized fluid, and which is locked mechanically in this position by screws.

    Abstract: A valve includes a central valve component with an integral housing molded therearound. During the molding of the housing a seal is held against the valve component by spaced fingers of a tool. After molding is complete and the tool is withdrawn, plastic gripping fingers formed from plastic injected between the fingers of the tool during molding hold the seal against the valve component and the housing.

    Abstract: A ball valve having a novel seat arrangement whereby the seat rings, placed on opposite sides of the ball closure member, are each retained by a ferrule which is screwed into the valve body. The ferrule secures and positions the seat ring in a manner whereby the seat is advanced toward the ball to simultaneously form a seal between a counterbore in the valve body and the outer periphery of the seat, and, to preload the seat against the surface of the ball closure member, forming a seal therebetween. Such simultaneous forming of seals is assisted by a tapered conical surface of contact between seat rings and their respective ferrule. Thus, the advancement of the ferrule toward the seat results in a seal being established simultaneously between the seat and the body, and, the ball closure member and seat.

    Abstract: A ball valve having a valve body with inlet and outlet openings, a ball-shaped valve disposed within said body and having an opening extending therethrough, valve-operating means including a handle engaging the ball-shaped valve to rotate the ball from the open to closed positions. The ball-shaped valve which is freely movable within the housing has its opening aligned with the inlet and outlet openings when the valve is in the open position. When the valve is in the closed position, the opening in the ballshaped body is substantially at 90* to the outlet port so that the pressure of the fluid from the inlet urges the ball-shaped valve against a cooperating seat at the outlet port.
