# Industrial Specification: Pressure Actuator

## 1. Technical Definition
A device that converts control signals into mechanical motion to regulate pressure in a system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-100 bar**. Failure boundary: **125 bar (burst pressure) at 20°C, 110 bar at 150°C**, Mechanism: **Diaphragm yield stress exceeds 250 MPa (AISI 316L stainless steel) causing plastic deformation and seal failure**.

### 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 |
