# Industrial Specification: Valve System

## 1. Technical Definition
A system of valves that controls the flow, pressure, and direction of gases or fluids within a pressure compressor.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 bar**. Failure boundary: **150 bar (yield strength of 316L stainless steel at 150°C: 205 MPa)**, Mechanism: **Cavitation-induced erosion when local pressure drops below fluid vapor pressure (e.g., water at 20°C: 0.023 bar), causing implosive bubble collapse with microjet impacts exceeding 1 GPa**.

### 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 |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Particulate contamination exceeding ISO 4406 16/14/11 cleanliness level | 8 | Spool valve stiction with actuation force exceeding 50 N | Install dual 10-micron absolute filters with differential pressure monitoring at 0.5 bar |
| Thermal cycling between -20°C and 150°C at 5 cycles/hour | 8 | Seal extrusion through 0.1 mm clearance at 100 bar | Implement PTFE backup rings with 0.05 mm interference fit and thermal expansion compensation |
