Key Features & Advantages:

1. Superior Stability with a Double Flanged Connection

Engineered for maximum reliability in critical pipeline sections, our valve features a double flanged (flanged ends) design. This robust construction provides distinct advantages over wafer-type valves:

• Secure, Bolted Joints: The integral flanges on both sides enable a solid, gasketed connection directly to the pipeline flanges using through-bolts, eliminating dependency on line bolts.

• Ideal for Dead-End Service: This design withstands unilateral pipeline pressure, making it the perfect choice for isolation points, system terminals, or future line extensions.

• Enhanced Mechanical Integrity: It offers superior resistance to pipeline stress, vibration, and bending moments, ensuring a leak-proof seal and long-term system stability.

2. Extended Service Life with a Nylon-Coated Disc

The valve disc is engineered for durability and optimal performance through advanced surface treatment.

• Corrosion & Abrasion Resistance: The ductile iron disc is protected by a high-quality Nylon (Polyamide) coating. This layer significantly enhances resistance to chemical corrosion and abrasive particles in the media.

• Improved Sealing & Efficiency: The coating creates an exceptionally smooth, low-friction surface. This improves sealing contact with the seat, ensures bubble-tight shut-off, and reduces operational torque.

• Reduced Maintenance: By minimizing wear on both the disc and the seat, this feature directly extends the valve's service life and lowers the total cost of ownership.

3. Uncompromising Strength from GGG40 Ductile Iron Body

The foundation of this valve is built for resilience, using premium material for critical structural components.

• High-Strength Material: The valve body is cast from GGG40/500-7 Ductile Iron, known for its excellent tensile strength and good elongation (toughness).

• Impact & Pressure Resistance: This material provides exceptional resistance to mechanical shock and hydraulic pressure surges, ensuring reliable performance under demanding conditions.

• Durable Foundation: The robust body securely houses the internal components and provides a stable platform for the flanged connections, guaranteeing overall valve integrity.
