Sanitary Check Valve is widely used in many industrial areas, but many people still don't know where to use it and what it does. In fact, the meaning of the check valve is in its name (its main purpose is to prevent the medium from flowing back), thereby reducing the occurrence of accidents. The check valve is a valve whose opening and closing parts open or close automatically depending on the flow of the medium, so its characteristics are also deeply loved by the general public.

According to the structure, the check valve can be divided into three types: lift check valve, swing check valve and butterfly check valve. According to the material, it can be divided into five types: cast iron check valve, brass check valve, stainless steel check valve, carbon steel check valve and forged steel check valve. From the above aspects, we understand that different characteristics have different classifications. As a check valve, it does not refer to a single valve, but a general term for multiple valves.

Let's take an example to learn more about the work of a check valve. For example, if your water heater valve is equipped with a check valve, will water come out when you open the check valve, and it can be hot water, but when you close the valve, will the water stop flowing? This is actually a check valve. But what I want to say here is that the purchase of check valves is a very important issue. If you buy a batch of inferior check valves with poor quality. Then imagine what problems will arise, especially when you turn on the hot water in the bathroom. If the check valve fails and is not closed, the hot water will spray out. If the check valve fails and does not obey, when it is opened or closed, it makes no difference whether it is opened more or less, will it accidentally hurt the skin? So this series of questions is to express an important thing, that is, when purchasing a check valve, everyone must check it carefully to see whether it is qualified or not, whether it has passed the 3C certification and other details. Remember, you must not buy it casually for cheapness. If there is a problem, it will be too late to regret. Therefore, it is very important to choose a manufacturer with guaranteed quality and national certification. This is not only responsible for purchasing but also responsible for yourself.
