# Industrial Specification: Pilot Valve (if applicable)

## 1. Technical Definition
A small valve that controls the operation of a larger main valve in pneumatic systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-10 bar**. Failure boundary: **15 bar differential pressure across pilot orifice**, Mechanism: **Plastic deformation of the pilot spool due to Bernoulli principle-induced pressure differential exceeding yield strength of 316 stainless steel (205 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.

- **Caution**: 

### Q: What is the primary function of a pilot valve in machinery manufacturing?
**A**: A pilot valve controls the operation of larger main valves in pneumatic systems, enabling precise regulation of air flow and pressure for industrial machinery.

### Q: Which materials are best for pilot valves in corrosive environments?
**A**: Stainless steel pilot valves offer excellent corrosion resistance, while engineering plastics like POM and Nylon provide chemical resistance and durability in harsh conditions.

### Q: How do I maintain pilot valves in pneumatic systems?
**A**: Regular maintenance includes inspecting the solenoid coil, cleaning the valve spool/poppet, checking spring tension, and ensuring the valve body is free from debris to prevent operational failures.
