ABSTRACT:
A bidirectional rotary valve capable of use in high pressure flowpaths includes a pair of removable end retainers defining aligned ports and having a single rotatably mounted disc closely positioned therebetween. The disc has ports corresponding to those of the end retainers and is operated by link means coupled to an operating rod slidably mounted in the valve body. Rotation of the disc changes the alignment between its ports and those in the end retainers for controlling flow. The disc is loosely mounted on a bearing pin that is also loosely fitted in the end retainers to permit slight lateral movement of the disc and ready disassembly of the valve. The disc is constructed such that it will flex to a greater degree for a given pressure than the end retainers.
