Duo-Chek Check Valves Compared to Conventional Swing Check Valves

Duo-Chek® high performance non-slam check valves are available in the sizes, pressure classes and configurations required to meet the most demanding of applications.

The Duo-Chek® wafer valve design is generally stronger, lighter, smaller, more efficient and less expensive than conventional swing check valves. Its design meets API 594, is approximately one fourth the face to face dimension and 15% to 20% the weight, on most popular sizes, making them less expensive than a swing check valve. It is much easier to install between standard gaskets and line flanges. The savings compound during installation due to ease in handling and only one set of flange studs is required. Therefore, it is more cost effective to install, and also to maintain.
