Duo-Chek® high-performance non-slam check valves are renowned for their dual-plate design, featuring two spring-loaded plates that ensure tight shutoff. These plates are responsive to flow, opening and closing automatically when flow stops or reverses, thus providing non-slam performance and mitigating water hammer. Constructed with rugged, corrosion-resistant materials, Duo-Chek® valves are capable of enduring severe operating conditions and are compliant with major industry standards.
Available in a broad range of sizes, pressure classes, and configurations, Duo-Chek® check valves offer reliable performance, tight shutoff, and long service life, making them indispensable across various industries such as oil and gas, chemical, power, and water treatment. With over 50 years of heritage, Duo-Chek® valves are globally trusted solutions to prevent backflow and protect equipment in the most challenging applications.
Duo-Chek® valves have long been the standard for low-pressure drop flow reversal protection. These valves are made from cast iron, cast steel, stainless steel, and a broad variety of exotic materials. Duo-Chek offers retainerless designs to API 594 end-to-end dimensions in steel bodied wafer and lug style with a wide variety of trim materials including both metal and resilient seats. Valves come in sizes up to 88" and pressure ratings up to class 4500.
