Key Features & Advantages:

1. Premium C95400 Aluminum Bronze Disc for Superior Corrosion Resistance

The standout feature of this valve is its high-performance disc material, specifically selected for aggressive media.

• Exceptional Seawater & Chemical Resistance: **C95400 Aluminum Bronze** (Nickel-Aluminum Bronze) offers outstanding resistance to corrosion, pitting, and erosion in seawater, brackish water, and various chemical environments—significantly outperforming standard stainless steels in marine applications.

• High Strength & Wear Resistance: This alloy provides excellent mechanical strength and resistance to galling and wear, ensuring long-term reliability even in high-velocity flow conditions.

• Non-Sparking & Biostatic Properties: C95400 is non-sparking, enhancing safety in potentially hazardous atmospheres, and its natural biostatic properties resist marine growth, reducing maintenance in seawater systems.

2. Massive DN1200 Size Engineered for Large-Diameter Flow Control

Built to handle the demands of major infrastructure and industrial projects.

• Designed for High-Volume Flow: With a **DN1200 (48-inch)** nominal diameter, this valve is engineered to efficiently manage large flow rates in water transmission mains, cooling water intakes, and other high-capacity systems.

• Reinforced Large-Diameter Construction: The valve body and disc are specifically designed with reinforced structures to maintain rigidity and sealing integrity at this large size under PN16 pressure.

• Optimized Gear Operation: The valve is equipped with a heavy-duty **worm gear operator** providing the high mechanical advantage required for smooth, effortless manual operation of this large-diameter valve.

3. Robust PN16 Ductile Iron Body for Strength & Durability

The foundation of this valve is built for resilience and long service life.

• High-Strength Material: The valve body is cast from **GGG40/500-7 Ductile Iron**, a material known for its exceptional tensile strength, good elongation, and impact resistance—far superior to gray iron.

• Secure Double Flanged Connection: The integral flanges on both sides enable a solid, gasketed bolted connection to the pipeline, providing superior mechanical strength, resistance to pipeline stress, and making it ideal for dead-end service.

• Epoxy-Coated for Added Protection: The ductile iron body is protected with a durable **epoxy coating** (standard), providing an additional barrier against corrosion and extending the valve's service life in buried or exposed installations.
