# Industrial Specification: Solenoid Valve

## 1. Technical Definition
An electromechanically operated valve that controls the flow of gas in a Gas Control System.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-10 bar differential pressure, -20°C to 80°C ambient temperature**. Failure boundary: **Coil burnout at 105°C insulation temperature, seal degradation at 12 bar differential pressure**, Mechanism: **Joule heating exceeding Class B insulation rating (130°C) causes coil insulation breakdown; excessive pressure differential deforms elastomeric seals beyond 12% compression set limit**.

### 2.1 Analytical Physics Model
Governed by the **Pneumatic Actuator Theoretical Force**:

> **Primary Equation**: $F = P \cdot A \cdot \eta_{eff}$  
> **Engineering Impact**: Calculates real-world pushing/clamping force for rejectors.

| Symbol | Variable Definition | Localized Reference |

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

### Q: What materials are used in this solenoid valve for gas control systems?
**A**: This solenoid valve is constructed from durable brass and stainless steel for the valve body, with PTFE (polytetrafluoroethylene) seals and diaphragm to ensure reliable, leak-proof operation in gas control applications.

### Q: What are the main components in the BOM for this solenoid valve?
**A**: The bill of materials includes key components: plunger/armature for magnetic actuation, seal/diaphragm for fluid isolation, solenoid coil for electromagnetic operation, spring for return mechanism, and the valve body housing.

### Q: How does this solenoid valve regulate gas flow in machinery equipment?
**A**: The valve uses electromagnetic force from the solenoid coil to move the plunger/armature, which opens or closes the flow path. This electromechanical operation allows precise on/off control of gas flow in industrial systems.
