# Industrial Specification: Release Valve

## 1. Technical Definition
A safety component in a gas lift cylinder that controls pressure release.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15.0 MPa**. Failure boundary: **18.7 MPa (yield strength of 316L stainless steel at 150°C)**, Mechanism: **Plastic deformation due to hoop stress exceeding material yield strength (σ_θ = P·r/t &gt; σ_y)**.

### 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 |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Corrosive H2S gas concentration exceeding 50 ppm | 8 | Stress corrosion cracking at valve seat interface | Apply Inconel 625 cladding on sealing surfaces |
| Particulate contamination &gt; 10 μm in gas stream | 8 | Abrasive wear of poppet sealing surface | Install 5 μm absolute filtration upstream with differential pressure monitoring |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are available for the release valve?
**A**: Our release valves are manufactured using durable brass or corrosion-resistant stainless steel, suitable for various industrial environments.

### Q: How does the release valve ensure safety in gas lift cylinders?
**A**: The valve automatically releases excess pressure through its spring and diaphragm mechanism, preventing over-pressurization and potential equipment failure.

### Q: What are the main components of the release valve?
**A**: The valve consists of three key components: a valve body (brass/stainless steel), a spring for pressure regulation, and a seal/diaphragm to prevent leaks.
