Valve, <specify>

Valves are devices that regulate, control, or direct the flow of fluids, gases, or other substances through medical equipment and systems, functioning mechanically to enable inflation, deflation, insufflation, aspiration, or isolation of materials. They are used across diverse clinical contexts including anaesthetic gas scavenging, central vacuum systems for fluid aspiration, endoscopic procedures requiring lens cleaning and irrigation, and surgical applications involving trocar sleeves.
