Swing Check Valve

MVS Valves offers high-performance Swing Check Valves engineered to provide reliable and cost-effective backflow prevention across industrial, commercial, and municipal pipelines. These valves operate using a gravity or spring-assisted swinging disc mechanism that ensures unobstructed flow and closes promptly when reverse flow occurs, protecting systems from contamination and pressure surges.

The design enables full-flow capacity with minimal pressure drop, making these valves highly efficient for continuous and intermittent operations. Built to meet international standards such as API 598, MSS-SP-71, and BS 1868, MVS Swing Check Valves are trusted for their durability and consistent performance under demanding pressure and temperature conditions.

To meet a wide spectrum of industrial needs, MVS manufactures Carbon Steel Swing Check Valve Class 150 Flanged Ends, ideal for standard pipeline installations. For more demanding service conditions, the Stainless Steel Swing Check Valve Class 300 Flanged Ends and SS 304 CF8 Swing Check Valve Class 600 Flanged Ends provide enhanced corrosion resistance and long service life. In high-pressure environments, options such as SS 316 CF8M Swing Check Valve Class 900 Flanged Ends and Duplex Steel Swing Check Valve Class 1500 Flanged Ends offer superior mechanical strength and chemical resistance.

For aggressive or marine applications where enhanced durability is critical, MVS also offers the Super Duplex Bolted Cover Swing Check Valve Flanged Ends, ensuring maximum operational security in highly corrosive environments. Additionally, for compact piping systems, the Stainless Steel Swing Check Valve Threaded Screwed Ends provides a flexible and space-saving solution, retaining the same reliability and sealing integrity.

Available in both horizontal and Y-pattern cast configurations, MVS Swing Check Valves are constructed using materials like carbon steel, ductile iron, and high-grade stainless steels to suit a wide range of fluid media. These valves are easy to install, maintain, and operate—making them a preferred choice in sectors such as oil and gas, water treatment, chemical processing, and power generation.

Whether used in standard utility lines or more critical systems requiring high-pressure containment, MVS Swing Check Valves make sure dependable one-way flow and safeguard pipelines from reverse fluid movement while maintaining peak performance and minimal maintenance requirements.
