# Industrial Specification: Isolation/Control Valve (per outlet)

## 1. Technical Definition
A valve installed at each outlet of an inert gas supply manifold to isolate and regulate gas flow to individual downstream processes or equipment.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-25 bar at 20-150°C**. Failure boundary: **35 bar differential pressure across valve seat at 180°C**, Mechanism: **Seat material (PTFE) glass transition temperature at 327°C causes permanent deformation under combined thermal and pressure loading, leading to seat extrusion and loss of sealing integrity**.

### 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 |
| :--- | :--- | :--- | :--- |
| Particulate contamination (≥50μm silica particles) in inert gas stream | 8 | Seat erosion and scoring leading to 0.5 L/min leakage at 10 bar | Install 10μm absolute filter upstream with differential pressure monitoring (ΔP≥0.3 bar triggers maintenance) |
| Actuator positioner feedback potentiometer wiper wear (≥10⁶ cycles) | 8 | Position control hysteresis exceeding 2% of stroke causing flow oscillation (±15% of setpoint) | Replace potentiometer with non-contact Hall-effect position sensor with MTBF 100,000 hours |

## 3. Key Technical Parameters

## 5. Engineering Risks & FAQ

- **Caution**: 

### Q: What materials are recommended for isolation/control valves in chemical manufacturing applications?
**A**: For chemical manufacturing, common materials include stainless steel (316/304 for corrosion resistance), carbon steel (for strength), brass (for certain non-corrosive gases), and PTFE seals (for chemical inertness and temperature resistance). Material selection depends on the specific gas, pressure, temperature, and environmental conditions.

### Q: How does an isolation/control valve enhance safety in inert gas supply systems?
**A**: This valve isolates individual outlets on an inert gas manifold, allowing safe maintenance or emergency shutdown of specific downstream processes without affecting the entire system. It prevents gas leaks, controls flow precisely, and helps maintain inert atmospheres to avoid combustion or contamination in chemical processes.

### Q: What components are included in the bill of materials (BOM) for this valve?
**A**: The BOM typically includes the valve body, closure element (such as a ball or gate), stem, seals/gaskets (often PTFE), and an actuator (manual, pneumatic, or electric) for operation. These components ensure reliable isolation and flow control for each outlet in the inert gas system.
