Product Overview
TRLAN NPS3 Class150 RF full-bore ball valve floating ball is produced per API 6D, ASME and NACE MR0175 standards. Its body and adaptor use ASTM A995 5A duplex steel with F53 ball and stem for excellent anti-chloride corrosion, suitable for seawater, brine and acid fluids.
With R-PTFE seat, anti-static device and API607 fire-safe construction, it ensures zero-leakage sealing. It completes 3.0MPa shell, 2.2MPa hydro-seat and 0.6MPa air-seat tests. Full bore & RF flange design fits desalination, chemical and pulp industry piping.
Details of the Valves
5A Stainless Steel Body Delivers Superior Strength & Impact Resistance
Crafted from premium 5A stainless steel material, this 5A duplex steel ball valve boasts outstanding tensile strength and reliable impact resistance to cope with fluctuating high-pressure working conditions. The stainless steel alloy features excellent corrosion resistance against acidic, alkaline and moist medium, extending service lifespan in harsh chemical and water treatment pipelines. Its two-piece bolted body together with standard ANSI flanges ensures stable pipeline installation and tight sealing. Manual lever actuator enables quick on-off operation for efficient industrial fluid regulation.


ASME Standard Symmetric Flange Optimizes Even Stress & High-pressure Sealing
Built with ASME-standard flange end and symmetrically distributed bolt holes, this floating ball valve with drain achieves even clamping stress during pipeline assembly. Uniform bolt layout eliminates local stress overload and prevents clearance-induced leakage, while precision-machined flange surface perfectly cooperates with sealing gaskets for tight shutoff under high pressure. Following ASME dimensional specifications, the flange fits seamlessly with global standard industrial piping, streamlining field installation. Ideal for chemical, water and oil pipelines, it maintains consistent long-term leak-proof performance amid fluctuating working pressure.
Floating ball valve with drain for Easy Maintenance & Stable Sealing
Adopting classic three-piece bolted structure and cast from 5A stainless steel, the floating ball valve is designed specially with drain for easy maintenance as customer required. The split design permits partial disassembly for internal component maintenance without removing the whole valve from pipelines. Bolt locking uniformly compresses body joints to avoid medium leakage, paired with ASME standard flange ends for standardized pipe connection. Equipped with a manual lever handle, it realizes quick on-off control while sustaining stable sealing under regular high-pressure working conditions.
