# Industrial Specification: Delivery Valve

## 1. Technical Definition
A precision valve component within a fuel injection pump that controls the release of pressurized fuel to the injectors.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **150-2000 bar**. Failure boundary: **Exceeds 2200 bar or drops below 100 bar**, Mechanism: **Cavitation erosion at pressures below 100 bar due to vapor bubble collapse on valve surfaces; plastic deformation above 2200 bar exceeding yield strength of hardened steel (typically 1600 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.
