# Industrial Specification: Control Valve Manifold

## 1. Technical Definition
A multi-port valve assembly that directs and regulates fluid flow within a leak testing system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-25.0 bar**. Failure boundary: **28.5 bar differential pressure across any single valve seat**, Mechanism: **Cavitation-induced erosion at valve seats when local pressure drops below fluid vapor pressure (0.023 bar for water at 20°C), causing material fatigue and seal degradation**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
