One、Is stainless steel or pure copper better for corner valves?
1. From a quality perspective, stainless steel angle valves are undoubtedly superior to copper ones. Stainless steel possesses higher hardness and better corrosion resistance. While high-quality stainless steel angle valves from reputable manufacturers can last for decades without leakage or corrosion, cheap stainless steel angle valves are of significantly lower quality due to serious cost-cutting measures. These valves are prone to damage and failure within a short period.
2. Copper angle valves are also an option. However, it's best to purchase those that are die-cast and molded, and avoid using sand casting products as much as possible, as their quality is generally poor.
Two. What are the best practices for selecting corner profiles?
1、 Check the material
Currently, the market offers three main types of corner valves: stainless steel, solid copper, and zinc alloy. As mentioned above, stainless steel and solid copper corner valves are preferable to zinc alloy corner valves. According to our understanding, zinc alloy corner valves have poor quality, a very short lifespan, and are prone to leaks. Therefore, it is best to avoid purchasing zinc alloy corner valves.
2、Inspect the valve
The valve components include ceramic valves, ball valves, and ABS valves. Ceramic valves are preferred for residential use due to their smooth operation, long lifespan, and relatively higher cost. Other valve types are typically used in industrial applications. Rubber rotary valves are difficult to operate and are now largely obsolete.
3、Inspect the handle
The materials commonly used for faucet handles include zinc alloy, stainless steel, brass, and ABS plastic. ABS plastic is designed to prevent burns, while zinc alloy is a common choice. Stainless steel and brass are more durable and have a higher price point.
