The 2PCS stainless steel flanged floating ball valve is a Q41F standard industrial floating ball valve with side-entry two-piece split body structure. Different from fixed ball valve, its spherical core adopts floating design, which can move slightly to press the sealing seat tightly to achieve zero leakage sealing effect. It only needs small torque to finish 90° rotary opening and closing action, with ultra-low fluid resistance in fully open state.
The valve supports full bore and reduced bore flow channel customization, equipped with integrated fire-safe structure, built-in anti-static device and low-emission optimized stem. It has multiple pressure grades and connection types, compatible with diversified automatic driving parts, widely used in water treatment, petroleum, chemical, gas and food industrial pipelines for medium cut-off and diversion work.
● Fire Safe Design: Standard fireproof structure inside the valve, keep structural integrity and sealing performance stable under sudden fire conditions, avoid medium leakage safety accidents.
● Built-in Anti-Static Device: Professional static conduction structure can export static electricity generated by fluid friction timely, eliminate static ignition risk for flammable gas and oil medium.
● Low Emission Optimized Stem: Polished packing and sealing structure reduce volatile harmful gas leakage, meet global environmental protection emission standards.
● Labor-saving 90° Operation: Floating ball match optimized sealing surface, small rotary torque, easy manual or automatic switch control.
● Detachable 2PCS Structure: Side entry split design, convenient on-site disassembly, cleaning and maintenance without cutting pipeline.
