# Industrial Specification: Discharge Valve

## 1. Technical Definition
A valve component that controls the release of blended pharmaceutical powder from the blending machine.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 bar differential pressure**. Failure boundary: **4.2 bar differential pressure sustained for &gt;30 seconds**, Mechanism: **Elastomer seal extrusion through valve seat clearance exceeding 0.15 mm due to differential pressure exceeding seal material yield strength of 2.8 MPa**.

### 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 |
