Ball valve structure characteristics
① The seat is double sealing, each seat can function separately to cut off the medium of inlet and outlet to achieve double cut, meanwhile, when the fluid medium in the valve gas fied as the temperature is rising which also causes the rapid rising in pressure, The medium in valve body can push the seat by its self function to decrease the pressure and ensure the safety of the valve.
② Blow-out proof stem structure: An opening ring is placed at the middle of the stem to prevent stem blow out which may caused by the rapid rising of pressure .
③ Anti static structure: release the static to the ground to ensure the safety of the valve.
④ Drain structure: Draining device is designed at the bottom of the main body, and venting device is also designed at the top of the main body.
