The reduced-port floating ball valve achieves sealing through medium pressure-driven ball displacement, where the ball compresses the downstream seat under fluid action to form a metal-nonmetal composite seal. It features 90° rotation for opening/closing, with low flow resistance, rapid cutoff, and compact design. The valve adopts a bottom-mounted stem anti-blowout design and accommodates multi-material sealing rings (e.g., PTFE, elastomers).
