Technical details and manufacturing context for Fluid Control Valve

Definition
A critical component within medical device systems that precisely manages fluid flow rates, pressure, and direction. Used in applications such as infusion pumps, dialysis machines, anesthesia delivery systems, and diagnostic equipment to ensure accurate dosing, patient safety, and system reliability.
Working Principle
Operates by opening, closing, or partially obstructing fluid passageways using mechanical, pneumatic, or electromechanical actuation. Common types include solenoid valves, pinch valves, check valves, and proportional valves that respond to control signals to achieve precise flow regulation.
Common Materials
Medical-grade stainless steel, PTFE (Polytetrafluoroethylene), Medical-grade plastics, Ceramic
