摘要： A valve having a valve closure member in a valve housing is provided. The valve closure member has a shaft received within an aperture of the closure member and extending out of the housing. One or more locking apertures are formed between an inner surface of the aperture of the valve closure member and an outer surface of the shaft, the locking apertures being angled outward from an axis of the shaft and toward the interior end of the shaft. One or more locking members are inserted into and engage each of the locking apertures, the locking members securing the position of the shaft relative to the valve closure member such that rotation of the shaft rotates the valve closure member between an open position and a closed position and such that internal pressure from within the valve housing increases the engagement between the locking members and the locking apertures.

摘要： A plug for a fluid valve has a stem extending along an axis between a first end and a second end, a tip secured to the first end of the stem, a plug body mounted to the stem toward the second end relative to the tip, and a valve seat between the tip and the plug body. The valve seat has a sealing surface that extends past an outer perimeter of the tip and is sized to engage a valve ring of the fluid valve, the valve seat defining an annular space that permits radial movement of the valve ring relative to the axis of the stem to align with the valve ring as pressure is applied to the valve seat.
