# Industrial Specification: Heating Medium Control Valve

## 1. Technical Definition
A valve that regulates the flow of heating medium (typically steam, hot water, or thermal oil) within a heating system to control temperature.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-25 bar at 20-180°C**. Failure boundary: **28 bar internal pressure differential at 200°C**, Mechanism: **Thermal expansion differential between valve body (carbon steel, α=11.5×10⁻⁶/°C) and seat (stainless steel 316, α=16.0×10⁻⁶/°C) causing seat deformation and leakage**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| f | Friction Factor | Engineering Constant |
| L | Pipe Length | Engineering Constant |
| v | Velocity | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Water hammer pressure surge exceeding 35 bar | 8 | Valve stem shear at 450 MPa stress concentration | Installation of accumulator with 0.5 m³ capacity and 10 bar pre-charge pressure |
| Steam condensate accumulation below 100°C saturation temperature | 8 | Cavitation erosion at vapor pressure of 1.013 bar | Steam trap with 0.5 kg/min drainage capacity and thermal insulation maintaining 120°C minimum |
