Fireproof Structure Design
In case of fire during the use of valve, the seat ring made of PTFE or other non-metal material be decomposed or damaged under high temperature and cause higher leakage. The fire proof of seal ring is et between ball and seat so that after the valve seat is burnt out, the medium will push the ball rapidly towards the downstream metal seal ring to from the auxiliary metal-to-metal sealing structure which can effectively control valve leakage. In addition, the middle flange sealing gasket, which can ensure sealing even under high temperature. The fireproof structure design of floating ball valve conforms to requirements of API 607, API6FA, BS 6755.
