Introduction to Dual Plate Double Flanged Check Valve Dimensions

Dual plate double flanged check valves are essential components in industrial piping systems, designed to prevent backflow while maintaining reliable flow control. These valves feature two hinged plates that open with forward flow and close quickly to prevent reverse flow, making them ideal for applications requiring fast closure and minimal pressure drop.

Double flanged connections provide the most secure mounting option, with flanges on both ends that bolt directly to pipe flanges, allowing easy installation and removal without disturbing adjacent piping. This configuration is particularly suitable for larger valve sizes and high-pressure applications where system integrity is critical.

Manufactured according to API 594 standards, these valves are available in multiple ASME pressure classes from 150 to 2500, accommodating various pressure and temperature requirements. The compact design offers significant weight reduction compared to traditional swing check valves while providing superior sealing performance.

Proper valve selection requires accurate dimensional data including face-to-face lengths, flange dimensions, and pressure ratings. The following sections provide comprehensive dimensional specifications for dual plate double flanged check valves across all standard pressure classes, enabling engineers to select the correct valve size for their specific application requirements.
