1. **Limited Temperature Range** While U-PVC is strong, it has a **temperature limitation** (typically **-10 C to 60 C**). Exposure to extreme heat or cold may cause warping or brittleness, restricting its use in high-temperature applications.

2. **Pressure Limitations** U-PVC valves are generally rated for **moderate pressure ranges** (usually up to **16 bar / 232 psi**). High-pressure systems may require reinforced or metal valves.

3. **UV Degradation Over Time** Although U-PVC is UV-resistant, prolonged outdoor exposure without proper shielding (e.g., paint or covers) can lead to surface degradation, affecting aesthetics and minor structural integrity.

4. **Not Ideal for Abrasive Particles** While U-PVC is durable, it is **not as resistant to abrasive particles** as metal or reinforced plastic valves. In systems with high sediment or sand content, wear on the diaphragm or seals may occur faster.

5. **Limited Availability of Spare Parts** Compared to standard metal valves, finding replacement diaphragms or seals for specific Asahi Av models may be harder, depending on the region or supplier.

6. **Weight and Installation Constraints** U-PVC valves are **lighter than metal alternatives**, which can be an advantage for ease of handling but may require additional support in large pipelines to prevent sagging.

7. **Potential for Thermal Expansion** In fluctuating temperature environments, U-PVC may expand or contract slightly, which could affect sealing performance if not properly accounted for in installation.

8. **Higher Cost Than Basic PVC** While still cost-effective compared to metal valves, U-PVC diaphragm valves are **more expensive than standard PVC valves**, which may not offer the same sealing performance.
