The difference between ball valve Q341F and Q347F
Ball valves Q341F and Q347F are turbine driven soft sealing flange ball valve, Q341F is a fixed ball valve, Q347F is a floating ball valve
7: fixed ball valve, F: fluorine plastic valve seat sealStructural distinction:Floating ball: ball valve is floating, in the media under pressure, that the ball can produce a certain displacement, and tight at the outlet end of the sealing ring, to ensure that the export side seal, a single side forced seal.Fixed ball: the ball of the ball valve is fixed, the pressure does not produce movement, therefore, in the design, two sealing ring should be sufficient pre tightening force to ensure sealing, double sided forced seal.
Ball valves Q341F and Q347F are straight through flow, worm drive, flange connection, soft sealing form. Different from Q341F, it is a floating ball structure, and Q347F is a fixed ball structure.Model meaning: Q34 worm gear flange ball valve, 1: floating ball valve;
