The Sealing System
The ball togather with the two sealing elements at the inlet and outlet of the ball valve, forms a single system the pressure of themedium process the ball agains the sealing element at the outlet part, but at the same time process the sealing element at the inlet part against ball. The reulting double sealing effect means inceased service reliabity. Both seals, act simultaneously. The sleeve surronding the out edges of the diaphragm disc seals the ball valve to atmosphere.
