J-VALVES
C95800 Triple Offset Lug Butterfly Valve
Nickel Aluminum Bronze Construction: Valve body is cast from C95800 nickel aluminum bronze per ASTM B148 standard, featuring exceptional seawater corrosion resistance and high tensile strength for offshore and corrosive fluid applications.
Triple Offset Geometry: Three-offset design between disc and seat achieves genuine metal-to-metal tight sealing with minimal frictional wear, delivering superior sealing performance and extended service life.
Lug End Connection: Lug-type ends comply with ASME B16.5 specification; piping on both sides can be detached independently for convenient maintenance and system modification.
Metal Sealing Structure: Valve seat is hardfaced with stainless steel or nickel-based alloy to withstand high temperature and abrasive wear, suitable for high-temperature, high-pressure services and media containing solid particles.
Fire-Safe Construction: Designed in compliance with API 607, the valve retains reliable sealing integrity under fire accidents to avoid hazardous fluid leakage.
Built-in Anti-Static Device: Integrated anti-static assembly eliminates static accumulation and mitigates potential fire and explosion hazards.
Anti-Blowout Stem Design: Optimized stem structure prevents stem ejection under unexpected pressure surges for enhanced operational safety.
Compact Layout: Small footprint and lightweight design save installation space compared with gate valves and ball valves, easy for on-site mounting and integration into existing piping systems.

Offshore Engineering: Applied on offshore platforms, subsea pipelines and seawater cooling systems to realize reliable medium isolation and flow regulation.
Seawater Desalination: Installed on reverse osmosis, pre-treatment and post-treatment pipelines to withstand severe corrosion from high-salinity seawater.
Shipbuilding Industry: Used in ballast water, bilge water and fire-fighting systems and can satisfy relative classification society certification standards.
Chemical Industry: Ideal for delivery pipelines of acid, alkali and corrosive gas to prevent medium leakage and secure stable production.
Power Industry: Deployed in cooling water and flue gas desulfurization piping to keep whole system efficient and steady.
Municipal Water Treatment: Suitable for seawater intake, drainage and sewage treatment projects for long-term stable running.
General Industrial Application: Used for cut-off and flow control of water, oil, gas and various common process medium.
High Operational Reliability: C95800 bronze material plus triple offset metal sealing supports stable operation under high temperature, high pressure and corrosive environment, decreasing maintenance frequency and production downtime.
Zero-leakage Sealing Performance: Unique triple offset structure achieves standard metal-to-metal zero leakage as specified in API 598, lowering risks of environmental pollution caused by medium escape.
Excellent Safety Performance: Fire-safe and anti-static design together with reliable sealing greatly reduces leakage hazards and protects equipment and site personnel.
Convenient Installation and Maintenance: Lug connection allows separate disassembly of bilateral pipelines, simplifying inspection, maintenance and later system upgrading.
Wide Working Condition Adaptability: Diversified material options and wide pressure & temperature scope enable the valve to adapt to various complex working conditions and different corrosive medium.
Superior Comprehensive Cost Performance: More compact and lightweight than gate and ball valves, it cuts installation cost and pipeline supporting investment while improving overall system safety.
