Main Features

• Durable Ductile Iron Construction
  Robust ductile iron body with a protective epoxy coating to provide excellent resistance to corrosion and demanding operating conditions.

• Reliable Soft-Sealing Disc
  Rubber-lined disc creates a dependable sealing surface, helping prevent reverse flow and ensuring secure shut-off.

• Optimized Flow Channel
  The internally streamlined passage allows water to flow smoothly while reducing turbulence and pressure drop.

• Responsive Swing Disc Mechanism
  The disc automatically reacts to changes in flow direction, closing promptly to minimize backflow and water hammer.

• Maintenance-Friendly Design
  A straightforward internal configuration with limited wear components simplifies inspection, servicing, and replacement.

• Flanged End Connection
  Designed with standard flange connections for secure installation, particularly suitable for horizontal piping systems.

• Built for Water Applications
  Designed for reliable long-term operation in clean water, wastewater, circulating water, and other common water-service applications.

Applications

• Municipal Water Infrastructure
  Suitable for water distribution, transmission, and drainage networks.

• Pump Discharge Systems
  Installed on pump outlet lines to help prevent water from flowing back toward the pump.

• Wastewater Treatment Facilities
  Suitable for various water and wastewater handling systems.

• Industrial Water Circulation
  Used in cooling, process-water, and other industrial circulating-water pipelines.

• Building Water & Fire Protection
  Applicable to building water supply networks and fire protection piping systems.

Precision Valve Manufacturing

Professional Valve Manufacturer | Integrated Manufacturing

Raw Material

We select high-quality raw materials according to product specifications and international standards. All incoming materials are carefully inspected to ensure chemical composition, mechanical properties and traceability.

Forging & Casting

Advanced forging and casting processes are used to produce strong and reliable valve bodies and components. Strict process control ensures uniform structure, dimensional accuracy and excellent mechanical performance.

CNC Machining

Our CNC machining equipment provides precise and consistent processing of valve components. Critical dimensions, threads and sealing surfaces are strictly controlled to ensure accurate assembly and reliable sealing performance.

Shot Blasting & Coating

Valve surfaces are professionally shot blasted to remove rust, scale and impurities. Protective coatings are then applied according to customer requirements, providing excellent corrosion resistance and a durable surface finish.

Pressure Testing

Every valve undergoes strict pressure testing before shipment. Body and seat tests are performed according to applicable standards and customer specifications to verify pressure resistance and sealing reliability.

Quality Inspection

Our quality control team conducts comprehensive inspections throughout the production process. Finished valves are checked for dimensions, appearance, materials, pressure performance and overall quality before final approval and shipment.
