When it comes to the inner workings of water heaters, one may wonder why ball valves are the preferred choice over angle valves. Let's delve into the reasons behind this common practice.

Efficiency and Durability

Ball valves are known for their efficiency and durability. These valves have a simple design with a ball inside that controls the flow of water. This design allows for a quick and easy shut-off, reducing the risk of leaks and ensuring smooth operation.

Less Restriction

Compared to angle valves, ball valves offer less restriction to the flow of water. This means that water heaters equipped with ball valves can operate more efficiently, providing a steady flow of hot water without any hindrances.


Ball valves are designed to last for a long time without the need for frequent maintenance or replacements. This longevity is crucial for water heaters, as they are often subjected to high temperatures and pressure. By using ball valves, manufacturers can ensure the longevity and reliability of their products.

Corrosion Resistance

Another advantage of ball valves is their resistance to corrosion. Water heaters are constantly exposed to water, which can lead to rust and corrosion over time. Ball valves, with their corrosion-resistant materials, are better equipped to withstand these harsh conditions, ensuring the longevity of the water heater.


In conclusion, the use of ball valves in water heaters is a strategic choice based on efficiency, durability, less restriction, longevity, and corrosion resistance. These valves play a crucial role in ensuring the smooth operation and longevity of water heaters, making them a preferred choice in the industry.
