---
### **Cons**
1. **Limited Corrosion Resistance**
- The **standard diaphragm material (neoprene or synthetic rubber)** is **not suitable for harsh chemicals, saltwater, or extreme corrosive environments**.
- Exposure to **oil, solvents, or high humidity** may degrade performance over time.
2. **Pressure and Temperature Limitations**
- Typically rated for **moderate pressures (up to 100 PSI / 7 bar)** and **temperatures (usually -20 C to 80 C)**.
- **Not ideal for high-pressure or high-temperature applications** (e.g., steam systems, extreme industrial processes).
3. **Lower Precision Compared to High-End Models**
- May exhibit **slight hysteresis or drift** in positioning, especially in **high-precision control systems**.
- **Not recommended for critical applications requiring sub-millimeter accuracy**.
4. **Material Degradation Over Time**
- The **diaphragm and seals** can **dry out, crack, or lose elasticity** with prolonged use, particularly in **dusty or contaminated environments**.
- Requires **periodic inspection and replacement** of worn components.
5. **Limited Customization Options**
- Fewer **specialized material or mounting variations** compared to premium actuators.
- If **custom sealing or housing modifications** are needed, additional costs may apply.
6. **Potential Leakage in Aggressive Conditions**
- In **high-vibration or dirty environments**, the **sealing integrity** may weaken, leading to **air or fluid leaks**.
- Requires **proper filtration and maintenance** to prevent premature failure.
7. **Not Ideal for Extreme Environments**
- **Not recommended for underwater, high-altitude, or space applications** due to material and pressure limitations.
- **Not suitable for cryogenic or ultra-high-temperature processes**.
