How to choose the material of the angle valve- Zhejiang Hongming Plumbing Technology Co, Ltd

The angle valve is insignificant for the overall decoration, so small that no one ever mentions it. But it's just a small angle valve. If you don't pay attention, it is very likely to make you bankrupt.

Where the angle valve is generally used and what type of angle valve is used, this needs to be configured differently according to the decoration design of each house.

Commonly used places are nothing more than the following:

1. The toilet water inlet; 2. The hot and cold angle valve under the wash basin; 3. The hot and cold angle valve of the balcony laundry tub; 4. The hot and cold angle valve of the kitchen sink; 5. The hot and cold angle valve of the water heater;

That is to say, the number of angle valves used by each company is at least about 10. Although it is inconspicuous, problems with each one can cause major losses.

Material selection of angle valve:

It must be distinguished here, the material and the valve core are two different things, the focus of the angle valve is the valve core, and the second focus is the main material.

Copper angle valves and ceramic valve cores are not pure copper but must be yellow. They are all electroplated. In terms of weight, pure copper weighs a lot. But it is impossible to have the so-called pure copper manufacturing, where the lead content is inevitable, but the lead content of a good pure copper angle valve reaches the standard, which is harmless to the human body.

Of course, the so-called pure copper used in the angle valve is almost zero, but the amount of copper contained is different. Let's take a look at the copper content of the faucet made by CCTV before. Sometimes the so-called big brands are not as good as our domestic ones.

Stainless steel angle valves and ceramic valve cores are much safer than copper-made lead content. Although it cannot be 100% lead-free, the total amount is many times lower than copper-made lead content. 304 stainless steel food grade materials, this is used very much in life, such as drinking cups, various thermos cups, and various stainless steel tableware. If lead is so easy to exceed the standard, then the market cannot allow it to exist.

As for the angle valves of zinc alloy and plastic on the market, this is simply not useful. It should be noted that ninety-nine percent of the angle valves that your home buys electrical appliances are made of zinc alloy. It can be used if you take advantage of it. However, it will not take long for 100% of the problems to occur. The chances of this luck are too great.

Copper or stainless steel angle valve is preferred, but this is not safe.

The angle valves in the house have a life limit. This is the same as home appliances. They cannot be used all the time. The key point is frequent observation and frequent replacement. If your household is a free zinc alloy angle valve, or you buy it at a cheap price, you usually have to replace it at most three or four years. Otherwise, it will not leak or break, and the consequences will be very serious.
