ABSTRACT:
An arrangement for providing access to the seal rings of a seatless high pressure valve includes an aperture in the valve body and a demountable sealed closure for the aperture. The sleeve within the valve body for transmitting the gland force to the seal rings is made in segments small enough for removal through the aperture to permit access to the seal rings. The valve seal rings may accordingly be replaced without disassembly of the major valve components including the valve plunger and gland.
