# Industrial Specification: Control Valve Assembly

## 1. Technical Definition
A complete assembly of valve components designed to regulate fluid flow within a system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-100 bar differential pressure, -40°C to 200°C fluid temperature**. Failure boundary: **Cavitation occurs at vapor pressure ≤ 0.023 bar absolute, mechanical failure at 150 bar differential pressure**, Mechanism: **Cavitation-induced pitting from Bernoulli's principle (P_vapor ≤ P_fluid), thermal fatigue from cyclic stress exceeding 250 MPa yield strength**.

### 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.
