Flanged Floating Ball Valve

Different from trunnion fixed ball valves, the floating ball core has free displacement margin. Medium pressure pushes the ball to compress the sealing seat actively, realizing automatic sealing compensation. The sealing effect improves synchronously with pressure rise, effectively solving poor sealing under low-pressure conditions. It achieves bidirectional bubble-tight zero leakage, adapting to frequent pressure fluctuation working conditions and ensuring long-term stable sealing performance.

Both ends adopt ANSI B16.5 standard flange structure, perfectly matching international standard pipeline flanges, gaskets and bolts. The integral double-flange casting enhances overall pipeline rigidity, effectively resisting pipeline vibration, thermal stress and pressure impact. Compared with wafer and threaded valves, flanged connection supports independent installation and disassembly without cutting pipelines, greatly simplifying on-site maintenance and replacement operations.

High-performance soft sealing materials such as PTFE and RPTFE provide ultra-tight zero leakage for normal-temperature clean media with low operating torque. Upgraded metal hard sealing structure adapts to high-temperature steam, high-pressure oil gas and fine particle-containing scouring media, avoiding soft seal aging, deformation and failure under harsh conditions. Dual sealing configurations fully cover conventional and severe service working conditions.

Built-in anti-static device conducts static electricity generated by friction between ball core and seat, eliminating explosion risks of flammable media such as natural gas and crude oil. API 607 fire-safe structure adopts graphite emergency sealing; when soft seal fails under high-temperature fire, it can still maintain effective shutoff to prevent medium leakage and fire spreading. Blow-out proof stem structure prevents stem ejection under extreme pressure, ensuring overall pipeline operation safety.

Full-bore design realizes straight-through pipeline with almost no flow resistance, maximizing medium transmission efficiency and reducing system energy consumption. Reduced-bore type features compact structure and cost advantage for general flow control scenarios. Simple floating ball mechanical structure with low operating torque reduces actuator matching cost. Standard modular structure facilitates quick inspection and parts replacement, lowering long-term operation and maintenance costs.
