Abstract

A limited restriction quick disconnect valve preferably for mounting between a container, like that involved in medical instrument sterilization system, and a transfer line for passing a sterilization agent thereto. The valve is for mounting at a bulk head female connector section into the container wall and includes a stem with side ports formed therein that intersect a passage that is open to within the container, the stem for receiving, as a closure device, a resilient sleeve fitted, in sealing arrangement, thereover. A closure ring section, that is connected to the transfer line, is provided for fitting onto a retaining ring of the bulk head female connector. The closure ring section includes a cylindrical shaft that is arranged axially therein that includes a forward end for engaging and compressing the resilient sleeve when the coupling ring is fitted onto the retaining ring, the resilient sleeve when compressed to bow outward around its mid portion, lifting the sleeve interior surface off from and opening the side ports, providing a passage from the container to the transfer line. For cleaning after use, the resilient sleeve can be pulled off the stem and replaced with another resilient sleeve and the interiors of the bulk head female connector and coupling ring section are open, have no moving parts, for facilitating cleaning.
