# Industrial Specification: Flow Control Valve

## 1. Technical Definition
A valve that regulates the flow rate of coating material in a precision coating applicator system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15.0 bar**. Failure boundary: **18.3 bar differential pressure**, Mechanism: **Cavitation-induced erosion at vapor pressure threshold of coating material (0.023 bar absolute at 20°C)**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

| Symbol | Variable Definition | Localized Reference |
