Abstract
A disposable valve, including a body having a plurality of ports and a core which is telescoped in the body and is rotated therein to provide connections between various ports, is provided with an improved arrangement for rotatably securing the core in the body and for halting its rotation at predetermined positions. The core is provided at one end with a splined bore, and is rotatably secured within the body by means of a fastener having a threaded shaft portion designed to be press-fitted into the splined bore. The body includes a boss which protrudes from it at one end, and the core includes a protruding member positioned to engage the corners of the boss so that the rotation of the core is halted. Both the boss and protruding member are encircled by a skirt formed on either the body or core to protect them from physical damage.
