valveis

Valveis is a term used in certain engineering contexts to denote a configurable family of valve devices designed to regulate the flow of liquids or gases within a piping or microfluidic network. The concept emphasizes modularity and reconfigurability, allowing a system to be adjusted by combining multiple valveis units in various arrangements to achieve the desired flow characteristics.

Valveis typically consist of a valve body with one or more ports, a sealing element or seat, and an actuator that moves the sealing element to open or close the flow path. Actuators can be mechanical, electric, pneumatic, or hydraulic; some designs incorporate sensors and closed-loop control for precise flow regulation.

Variants of valveis may include straight-seat designs, globe-like configurations, and needle-like variants optimized for low leakage and high precision. Materials are selected for chemical compatibility, pressure, and temperature requirements, often including stainless steel, brass, certain polymers, or ceramic coatings. In microfluidic applications, valveis are designed for micron-scale channels and solvent compatibility; in industrial settings, they may be rated by maximum pressure and Cv value.

Applications for valveis include laboratory automation, pharmaceutical manufacturing, water treatment, and other process industries where accurate, reliable flow control is needed. They can be integrated into automated control systems, enabling digital or analog control of flow for experiments, production lines, or environmental control.

Etymology: the name valveis appears to derive from "valve" with a Latin-sounding suffix; usage varies by region and discipline.
