Abstract: A valve has a valve body, a valve member, a bonnet, an anti-loosening stem and multiple fillers. The valve member is mounted inside the valve body, and has a first mounting part and a groove that is defined annually in the first mounting part. The anti-loosening stem is mounted through the valve body, and has multiple embedding elements and a second mounting part that is mounted in the first mounting part.
