Dual Plate Check Valve

Dual Plate Check Valve Manufacturer

MVS Valves manufactures high-performance Dual Plate Check Valves engineered for reliability, efficiency, and space-saving design in various flow control systems. This type of valve is known for its lightweight construction, compact wafer body, and quick-closing functionality—making it the ideal solution for preventing backflow in both vertical and horizontal pipelines.

Designed in compliance with API 594 and API 598 standards, the Dual Disc Check Valve features a spring-loaded twin-door mechanism that ensures silent, non-slam operation even under fluctuating flow conditions. Often referred to as a Double Disc Check Valve, Duo Wafer Check Valve, or Dual Flapper Check Valve, this versatile product is built to outperform conventional swing or lift check valves in strength, response speed, and space utilization.

Our Dual Plate Check Valves are available in various materials to match your specific media and application needs, including Carbon Steel Wafer Body Dual Plate Check Valve Class 150, Stainless Steel Dual Disc Spring Loaded Wafer Check Valve CL 150, SS 304 CF8 Wafer Body Dual Plate Check Valve Class 150, and SS 316 Dual Disc Spring Loaded Wafer Check Valve CL 150. For aggressive or corrosive environments, MVS offers high-grade alloys like Duplex Steel Wafer Style Dual Plate Check Valve CL 150 and Super Duplex Wafer Type Dual Plate Check Valve Class 150, making sure longer life and consistent performance.

Every Dual Disc Spring Loaded Wafer Check Valve features a retainerless body design to eliminate potential leak paths, while also allowing for installation between standard flanges without special adaptors. Whether it’s a Wafer Pattern Twin Door Check Valve in cast steel or stainless steel, our product line supports seamless flow with minimal pressure drop and reduced maintenance downtime.

MVS also offers the Duo Wafer Check Valve Stainless Steel Carbon Steel variant, combining material flexibility with operational precision. From water treatment plants to petrochemical lines and high-pressure gas applications, these check valves provide efficient flow control without compromising safety or durability.
