IN-LINE REPAIRABLE TOP ENTRY BALL VALVE Abstract of the Disclosure An in-line repairable top entry floating ball valve having internal components that are replaceable through an access opening, closed by a valve bonnet, while the valve body is located within a flow line. The valve mechanism is provided with seats which may be of resilient nature and are sealed with respect to the spherical plug member by means of ball/seat spacers having interference sealing engagement between the plug and seats. The ball/seat spacers form sealing surfaces at one axial end for sealing engagement with the spherical plug member and sealing surfaces at the opposite axial end for sealing engagement with the seats and in spherically concentric relation with the plug to thus permit installation and removal of the ball/seat spacers in an arcuate motion about the spherical surface of the plug. With the stem in horizontal position and the plug member in closed position, the plug member is supported by the operating stem and a guide pin to prevent misalignment of the plug member while permitting the plug member to float downstream under the influence of pressure. The valve mechanism provides effective fire-safe sealing in the event the seats and seals of the valve become destroyed by excessive heat.
