safety valve seal
Thread Content
After the safety valve is calibrated, there is an additional lead seal. Isn't this what normal safety valve seals are supposed to do?
This should be the lead seal that manually activates the handle, but it seems to be able to move even if it is sealed like this. Generally, it is more suitable to have a hole at the end of the handle and a ring on the valve body with a lead seal.
O(∩_∩)Ohaha~! This is funny. Let me tell you, there is generally no lead seal on the handle. This is to prevent you from affecting the take-off pressure when pulling the handle during transportation and loading. After installation, it needs to be dismantled. However, generally no one will pull it out. Only when the air leaks does someone pull it out. Since your lead seal seems to be made of plastic and comes with it when it leaves the factory, can the person who checked it just put a brand on it for you? Illegal operation.
I understand, this is redundant

It doesn’t matter what you do, the key is to verify the reality
