In the current market, angle valve has all copper, stainless steel, zinc alloy and other materials. But what material is good to choose?
Angle valve made of brass
Advantages: all-copper angle valve is generally used ceramic spool, not easy to oxidation and will not rust, the service life of more than 10 years, and disassembly is particularly easy.
Disadvantages: the traditional copper angle valve contains lead, the use of a long time will appear copper green, the color will darken; in addition, the copper angle valve is relatively more expensive.
Angle valve made of stainless steel
Advantages: stainless steel angle valve is generally made of SS304, and does not contain lead, healthy and environmentally friendly; acid and alkali resistant, corrosion resistant, rust-free, durable and new.
Disadvantages: stainless steel angle valve contains chromium, relatively difficult to process, immature technology, the price is relatively high.
Angle valve made of zinc alloy
Advantages: zinc alloy angle valve is relatively inexpensive, easy to mass production, the appearance of bright and clean anti-fouling, not easy to rust.
Disadvantages: easy to oxidation, the general service life of only 2-3 years, very easy to break, and not easy to remove, it is recommended to try not to use.
Conclusion: Taking into account the service life, it is best to choose stainless steel or all-copper angle valve, generally can be used for more than 10 years; pay attention to identify the angle valve material, generally from the inlet along the light to look in, the wall has a small white dot is zinc alloy, yellow but very rough is iron, yellow or yellow-white and very smooth is copper material.
So how to select the best angle valves?
1, Angle valve material selection Considering the service life, the best choice of stainless steel or all-copper angle valve, generally can be used for more than 10 years; pay attention to identify the angle valve material, generally from the inlet along the light to look in, the wall has a small white dot is zinc alloy, yellow but very rough is iron, yellow or yellow-white and very smooth is copper material.
2, Angle valve spool selection the spool is the heart of the angle valve, close firmly, life years all depends on it, especially inside the seal and ceramic piece. Generally good angle valve are used ceramic spool, you can try the feel, feel too light with no time to leak, feel too heavy switch is very inconvenient.
3, Angle valve workmanship details When shopping, be sure to carefully check the details of the corner valve workmanship, such as whether the corner valve plating glossy shiny, whether the appearance of blistering or scratches, to feel smooth and flawless is better.
