# Industrial Specification: Pressure Regulator

## 1. Technical Definition
A device that maintains a constant output pressure regardless of variations in input pressure or flow demand.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-100 bar**. Failure boundary: **150 bar (diaphragm rupture pressure) or 0.3 bar (minimum differential pressure for stable regulation)**, Mechanism: **Diaphragm material yield strength (typically 316L stainless steel with 205 MPa yield strength) exceeded at 150 bar; Bernoulli principle disruption below 0.3 bar differential causing flow instability and cavitation**.

### 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 25 μm in fluid stream | 8 | Seat erosion and leakage with flow coefficient Cv deviation &gt;15% | Install 10 μm absolute filter upstream with differential pressure monitoring |
| Cyclic pressure fluctuations at 0.5-2 Hz frequency exceeding 20% of setpoint | 8 | Diaphragm fatigue failure at 10^5-10^6 cycles (based on Goodman diagram for 316L SS) | Pulsation damper installation with 0.1 L volume per 10 L/min flow capacity |
