The special “V” seating design introduced the self-adjusting seat to the isolation ball valve. This design does not rely on the built-in interference of conventional floating ball valves. It provides automatic compensation for pressure, temperature and wear. As these changes occur, the ball and seats are continuously snugged down into the “V” resulting in positive leak-tight shut off when using resilient seats. Maintaining a low pressure seal had been the most difficult condition for floating ball valves. The wedge effect on the ball and seats down the “V” assure continued low pressure sealing for the life of the seat. All Apollo Top Entry Valves have an “anti-static” feature designed in. All valve configurations also feature blow-out proof stems as standard.
