### **Cons**
1. **Limited Pressure Range**
- The valve is **rated for 0.3 MPa (3 bar) maximum**, which may be insufficient for **high-pressure applications** (e.g., heavy-duty hydraulic systems or extreme pneumatic tools).
- If higher pressure is required, a different model (e.g., SMC s **NCD series with higher pressure ratings**) would be needed.
2. **Electrical Power Requirements**
- The valve requires **24V DC or 120V AC**, which may not be ideal for **low-power or battery-operated systems**.
- Some applications may need a **separate power supply**, adding to system complexity.
