Dual plate check valves, also known as wafer check valves, are designed to prevent backflow in liquid, gas, and steam pipelines. Featuring two spring-loaded semicircular plates that pivot on a central hinge, these valves automatically close when flow reverses, preventing system damage and maintaining operational efficiency. Compact and lightweight, they can be installed between flanges without requiring additional support. Constructed from carbon steel, stainless steel, or alloy materials, dual plate check valves offer corrosion resistance, low pressure drop, and reliable performance. They are widely used in water treatment, chemical processing, power generation, and HVAC systems.
