# Industrial Specification: Sanitary Pressure Relief Valve

## 1. Technical Definition
Safety valve for pressure control in hygienic beverage processing systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-16 bar**. Failure boundary: **18.5 bar (spring compression exceeds yield strength at 450 MPa)**, Mechanism: **Spring material yield point exceeded due to overpressure, causing permanent deformation and loss of sealing force**.

### 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 |
| :--- | :--- | :--- | :--- |
| Corrosive fluid pH below 2.5 | 8 | Stainless steel 316L diaphragm pitting corrosion | PTFE-coated diaphragm with 0.5 mm thickness |
| Particulate contamination &gt; 50 μm in process fluid | 8 | Seat surface scoring leading to 0.1 mm³/s leakage | Upstream 40 μm absolute filtration with differential pressure monitoring |
