Technical details and manufacturing context for Fluid Control Valve

Definition
This fluid control valve is a precision component used in medical device systems to manage the flow of liquids, gases, or medical solutions. It is designed to regulate flow rate, pressure, and direction with high accuracy, ensuring reliable operation in applications such as infusion pumps, dialysis machines, anesthesia delivery systems, and diagnostic equipment. The valve 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, which respond to control signals to achieve precise flow regulation.

Typical technical parameters for this valve category include a nominal diameter of 2–50 mm (ISO 6708), an operating pressure range of 0.1–1.0 MPa, and a flow coefficient (Cv) of 0.01–5.0 (IEC 60534-2-3). Leakage rate is specified as ≤0.01% of rated Cv (ISO 5208, Class VI shutoff), and operating temperature ranges from -10°C to 80°C (ISO 5211). Response time is 10–50 ms (IEC 60534-4), control accuracy is ±1.0% of span (IEC 60534-4), and supply voltage is 24 V DC ±10% (IEC 61131-2). Power consumption is 2–10 W (IEC 60534-4), ingress protection is IP54–IP65 (IEC 60529), and weight ranges from 0.2–5.0 kg. Body material is typically 316L stainless steel (ASTM A240), and seal materials include PTFE/EPDM (ASTM D2000).

These values are directory reference ranges and must be verified for the specific model and application. Always confirm model-specific parameters and standards compliance with the legal manufacturer or supplier before procurement or use.
Working Principle
The valve regulates fluid flow by opening, closing, or partially obstructing the passageway. Actuation can be mechanical (manual or spring), pneumatic (air pressure), or electromechanical (solenoid or motor). The control signal, typically electrical, determines the valve position, allowing precise adjustment of flow rate and pressure. For proportional valves, the degree of opening is continuously variable, enabling fine control. Check valves allow flow in one direction only, preventing backflow. The valve's design ensures minimal leakage and fast response, critical for accurate dosing in medical applications.
