J-VALVES
Nickel Aluminum Bronze Material (C95800): The valve body is made of ASTM B148 C95800 nickel aluminum bronze, delivering outstanding seawater corrosion resistance, cavitation resistance and wear resistance, suitable for marine and chlorine-containing medium environments.
Top Entry Design: The bonnet opens from the top, enabling in-line disassembly and replacement of internal parts such as ball and seat. No need to remove the valve from the pipeline, greatly cutting maintenance downtime.
Full Port Design: The bore diameter of the ball matches the pipeline inner diameter, featuring an ultra-low flow resistance coefficient (high Cv value) and minimal pressure drop, perfect for systems with strict flow rate and energy efficiency requirements.
Optimized Low Resistance Flow Passage: The internal flow path is CFD optimized with smooth transitions and no dead flow zones, effectively reducing turbulence and energy loss.
Threaded Connection: Available with NPT (ANSI/ASME B1.20.1) or BSPT threaded connection for easy installation, suitable for piping systems with limited space.
Floating Ball Design: The ball floats freely under medium pressure and fits tightly against the seat, achieving reliable bidirectional sealing.
Fire Safe Design: Compliant with API 607 standard, maintaining sealing performance even under fire conditions to prevent medium leakage.
Anti-Static Device: Built-in anti-static structure prevents static accumulation and reduces fire and explosion hazards.
Blowout-Proof Stem Design: The valve stem adopts blowout-proof construction to ensure operational safety.
ISO 5211 Actuator Mounting Platform: Standardized mounting flange on the top for easy assembly with manual, pneumatic or electric actuators.
