Double Ball Valve (Parallel Ball Valve, Series Ball Valve) When it is necessary to cut off the pipeline, only one of the ball bodies needs to be rotated to cut off the pipeline. The other ball body only operates after the seat sealing component of the first ball body fails. The two ball bodies can also be operated alternately to extend the product's service life, achieving double block and double cut-off functions for the pipeline.
