The MV-51 Swing Disc Check Valve (represented by BV-09 DN40  in the illustration) from Alide is engineered to permit media flow in only one direction, automatically preventing backflow. Its main mechanism is a disc that swings on a pin (or hinge), sealing the flow path when the downstream pressure exceeds the upstream pressure, or when the flow ceases. The robust structure derived from Investment Casting for the body, cap, and disc ensures durable performance.

• Automatic Backflow Prevention: Operates without the need for external actuation, making it a reliable, fail-safe solution for protecting equipment and systems.
• High-Quality Construction: The valve body and other critical parts are manufactured using the investment casting process , featuring standard materials like CF8M, CF8, or CF3M, known for their corrosion resistance.
• Connection Flexibility: Equipped with thread options compatible with global standards such as ISO, BS, DIN, JIS, and ASME.
• Versatile Media Application: While commonly used for liquids, this check valve design is frequently utilized in gas applications (air check valve for gas) to prevent the back-siphoning of gas or compressed air.
