These Wafer Type Ductile Iron Valve Body Hard Back Seat Butterfly Valves deliver reliable, bubble-tight shut-off and durable flow control for demanding industrial applications. Engineered for efficiency and longevity.

1. this valve design features:

• Robust Ductile Iron Body: Provides exceptional strength, impact resistance, and superior corrosion protection compared to standard cast iron, ensuring long-term reliability under pressure.

• Space-Saving Wafer Design: Installs easily between ANSI/ASME or EN/DIN flanges, reducing weight, cost, and installation footprint – ideal for retrofit or space-constrained projects.

• Hard Back Seat Technology: Features a precision-machined, metal-to-metal seat (often stainless steel) that ensures zero leakage in the closed position, even after prolonged use or exposure to high temperatures/pressures. Superior to soft-seat alternatives for critical isolation.

• High-Performance Sealing: Combines the hard back seat with a resilient seat (EPDM, Viton, etc.) for bidirectional shut-off capability and low operating torque.

• Durable Disc & Stem: Typically utilizes a corrosion-resistant disc (e.g., ductile iron epoxy-coated, stainless steel) and hardened stainless-steel stem for smooth operation and extended service life.

2. Key Benefits:

Bubble-Tight Shutoff (Zero Leakage) | Compact & Lightweight | High Pressure/Temperature Capability | Bi-Directional Sealing | Low Maintenance | Corrosion Resistance | Long Service Life | ISO 9001 Certified.

3. Ideal For:

Chemical Processing, Power Generation (Water/Steam), HVAC, Oil & Gas (non-critical), Water Treatment, Marine Applications, and General Industrial Pipelines requiring dependable, leak-proof isolation.
