Series X

Series X

Hy-Grade Series X Wafer swing check valves are designed to meet ASME B16.10 Face-to-Face dimensions. The design features a high-performance, streamlined flow design with an unobstructed flow path, offering highly engineered material selection opportunities that can withstand high-pressure and high-temperature applications. This design differs from other check valves by incorporating an integrated flapper and pin, providing strength at a critical location. Typical swing check valve designs feature multiple components for the flapper assembly, including bushings, nuts, bolts, and hinge pins. These components wear out over time or come apart, leading to check valve failure.

Face-to-face dimensioning per ASME B16.10

Disk movement is contained to the body of the valve, with no end connection restraints

Seat insert is press-fit into the body, providing a tight seal and no external leak paths or fugitive emissions

Highly engineered solutions, designed and sized for specific application requirements

Severe service options available: tilted seat, disc stops, increased pin diameter

Low cracking pressure capabilities

Integrated flapper-pin design reduces the number of internal components, reducing the points of failure

WedgeSeal Metal-to-Metal angled seating surface available as an option for disc seating

Large unobstructed bore allowing for maximum flow capacity with extremely low pressure drops

Reduced bore options are available

Low-weight disc options and spring assistance combine to ensure the quickest and smoothest response to flow changes

Double-wound torsion spring assist for instant sealing and anti-chatter operations

Fire safe design for metal and soft seated valves
