2205 Duplex Stainless Steel Material: The valve body, disc, and key components are made of 2205 duplex stainless steel, offering a perfect balance of high strength (twice that of austenitic stainless steels) and exceptional corrosion resistance, making it suitable for aggressive media and high-pressure systems.
High-Pressure Design: Optimized structural integrity to withstand Class 1500LB (PN260) pressure ratings, ensuring reliable operation in high-pressure pipelines.
Swing Disc Mechanism: Adopts a swing-type disc design that automatically opens with fluid flow and closes promptly when flow stops, effectively preventing backflow and minimizing water hammer effects.
Flange Connection: Equipped with standard flange connections (conforming to ASME B16.5) for secure and leak-tight installation, ensuring compatibility with existing pipeline systems.
Fire-Safe Design: Complies with API 607 standards, maintaining sealing integrity even in fire emergencies to prevent medium leakage and enhance operational safety.
Anti-Static Device: Integrates built-in anti-static components to dissipate static charges, reducing the risk of sparks and potential explosions in hazardous environments.
Stem Blowout Prevention: Features a stem blowout-proof design, ensuring the stem remains securely in place under high pressure, enhancing operational safety.
Compact & Durable: Compact structure with high mechanical strength, facilitating easy installation and long service life with minimal maintenance.
