Dispersed fully welded ball valve 04

The valve seat of the fully welded ball valve 04 consists of a PTFE sealing ring and a spring. It has a strong adaptability to changes in pressure and temperature, and will not cause any leakage within the range of use. In order to ensure the freedom of movement of the valve seat, it should be cleaned once a year. The well regularly checks the sealing of the valve through the drain nozzle. The thrust washer support of low friction material is used to push the pressure to the valve stem, so that the valve stem only serves to transmit torque.
