1. Double-channel O- ring prevents leakage of valve stem
2. The anti-blow stem is installed from the inside of body, and the step of stem installation part ensures the safety of the valve stem under various pressures and is not blown out.
3. When the soft sealing material is destroyed by fire, the metal valve seat is pressed against the metal sphere, and the pipeline is cut off to prevent the medium from leaking.
4, O-rings and gaskets to prevent leakage between the body and bonnet
5. Floating seat with pre-tensioned spring ensures sealing even at low pressure
6, injection sealant (grease) device, in case of emergency, through the injection of glue to prevent leakage of the stem
7. Injection sealant (grease) device, in case of emergency, through the injection of glue to prevent leakage of the seat
8, screw plug, discharge dirt inside the valve cavity
