Stopcock (one way)

A one-way stopcock is a valve device used to control the flow of fluids or gases in one direction only. Commonly used in medical and surgical applications, such as fluid management, catheter systems, and infusion lines, it ensures that flow is restricted to a single direction, preventing backflow or contamination. Typically constructed from medical-grade plastic or stainless steel, it features a lever or rotary control to open or close the flow path.
