# Industrial Specification: Filling Head

## 1. Technical Definition
A precision dispensing component that controls the flow of chemical liquids into drums during automated filling operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-6.0 bar (7.25-87.0 psi) at 20°C**. Failure boundary: **8.5 bar (123.3 psi) differential pressure across the nozzle**, Mechanism: **Cavitation-induced erosion at vapor pressure threshold of 0.0234 bar absolute for water at 20°C, amplified by Venturi effect in nozzle constriction**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| \delta_d | Dispersive | Engineering Constant |
| \delta_p | Polar | Engineering Constant |
| \delta_h | Hydrogen | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Particulate contamination exceeding 25 μm in 316L stainless steel fluid path | 8 | Nozzle orifice erosion increasing from 0.5 mm to 0.8 mm diameter | Install 10 μm absolute filtration with differential pressure monitoring at 0.3 bar threshold |
| Cyclic thermal stress from 20°C to 80°C temperature swings during CIP cycles | 8 | Fatigue cracking at brazed joint between 316L body and Hastelloy C276 nozzle | Redesign with monolithic construction using Alloy 625 and controlled cooling rate of 10°C/min maximum |
