AWWA C515 Flange Type Ductile Iron Resilient Seated Gate Valve

Reliable Isolation Valve for Modern Water Distribution Systems

The BOPIN AWWA C515 Flange Type Ductile Iron Resilient Seated Gate Valve is specifically engineered for municipal water supply, water treatment plants, irrigation systems, fire protection networks, and industrial water pipelines. Manufactured in accordance with the AWWA C515 standard, this resilient seated gate valve combines lightweight ductile iron construction with an elastomer-coated wedge to deliver excellent sealing performance, long service life, and low operating torque.

Compared with traditional metal seated gate valves, the resilient seated design provides bubble-tight shutoff, eliminates seat leakage caused by corrosion, and requires less maintenance throughout its service life. With advanced manufacturing technology and strict quality control, BOPIN ensures every valve meets the demanding requirements of water infrastructure projects worldwide.

1: Features of BOPIN AWWA C515 Resilient Seated Gate Valve

- Durable Ductile Iron Body

The valve body and bonnet are manufactured from high-strength ductile iron, offering excellent mechanical properties and impact resistance while reducing overall valve weight. Ductile iron provides superior toughness compared to gray cast iron, making it ideal for underground water distribution systems.

- Fully Encapsulated Resilient Wedge

The gate is completely encapsulated with premium EPDM or NBR rubber, ensuring outstanding sealing performance and corrosion protection. The resilient wedge conforms tightly to the valve seat, delivering zero visible leakage even after years of operation.

- Low Operating Torque

Precision machining of the stem threads and optimized wedge geometry significantly reduce friction during opening and closing. This allows manual operation with minimal effort and improves compatibility with electric actuators, gearbox operators, and other automation systems.

- Fusion Bonded Epoxy Coating

All internal and external surfaces are coated with fusion bonded epoxy, typically exceeding 250 microns in thickness. The coating provides excellent resistance to corrosion, abrasion, and chemical attack while ensuring compliance with drinking water applications.

- Non-Rising Stem Design

The compact non-rising stem design is ideal for buried installations and confined spaces. The stem remains protected inside the valve, minimizing exposure to environmental contaminants and reducing installation height requirements.

3: Advantages of AWWA C515 Resilient Seated Gate Valve

The resilient seated gate valve offers several advantages over conventional metal seated gate valves.

First, the rubber-coated wedge provides complete shutoff without relying on metal-to-metal contact. This minimizes leakage and extends the valve's operational life.

Second, the smooth waterway minimizes pressure loss and allows unrestricted flow when the valve is fully open.

Third, corrosion-resistant materials protect both internal and external components from harsh underground environments and chlorinated water.

Fourth, maintenance requirements are significantly reduced because the resilient seat compensates for minor wear while preventing internal corrosion.

Finally, the lightweight ductile iron construction simplifies transportation, installation, and maintenance, helping contractors reduce overall project costs.

4: Applications

The BOPIN AWWA C515 Flange Type Ductile Iron Resilient Seated Gate Valve is widely used in numerous water infrastructure projects, including:

• Municipal drinking water distribution systems
• Water transmission pipelines
• Water treatment facilities
• Pumping stations
• Fire protection systems
• Irrigation networks
• Industrial cooling water systems
• Commercial building water supply
• Wastewater treatment plants
• Utility infrastructure projects

Its reliable sealing performance makes it particularly suitable for systems requiring frequent operation and dependable isolation.

5: Quality Assurance and Testing

Quality is the foundation of every BOPIN valve. Each AWWA C515 resilient seated gate valve undergoes comprehensive inspection and testing before shipment.

Manufacturing includes dimensional inspection, material verification, machining accuracy checks, coating thickness inspection, assembly verification, and functional testing.

Every finished valve is subjected to hydrostatic shell testing and seat leakage testing in accordance with AWWA requirements. These rigorous inspections ensure each valve provides dependable sealing performance, structural integrity, and operational reliability in demanding service conditions.

Additional third-party inspections such as SGS, BV, TUV, Lloyd's Register, and customer-designated inspections are available upon request.
