# Industrial Specification: Sanitary Discharge Valve

## 1. Technical Definition
A specialized valve designed for hygienic discharge of blended food ingredients from mixing systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-6.0 bar (50-600 kPa)**. Failure boundary: **8.0 bar (800 kPa) differential pressure across valve seat**, Mechanism: **Seat material yield strength exceeded (316L stainless steel, 170 MPa yield strength) causing permanent deformation and loss of sealing integrity**.

### 2.1 Analytical Physics Model
Governed by the **Heat Sterilization F0 Lethality Model**:

> **Primary Equation**: $F_0 = \int_{0}^{t} 10^{(T-121.1)/z} dt$  
> **Engineering Impact**: Validates microbial reduction integrity for aseptic packaging.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| T | Process Temp (°C) | **$T \in [121-135]$ °C** (Per `temperature_range`) |
| t | Exposure Time (min) | Engineering Constant |
| z | Z-value | **10 °C** (Standard for *C. botulinum*) |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Particulate contamination exceeding 100 μm diameter in food slurry | 8 | Seat scoring and leakage at 0.1 L/min under 3 bar pressure | Install 80 μm upstream filtration with differential pressure monitoring |
| Thermal cycling between 4°C (refrigerated ingredients) and 85°C (CIP cleaning) | 8 | PTFE seat gasket compression set exceeding 15% permanent deformation | Implement controlled temperature ramp rates not exceeding 2°C/min during transitions |

## 3. Key Technical Parameters
