Product Description

Wafer Double Flanged Type Dual Plate Check Valve


Dual plate, or double-door, check valves consist of two plates hinged in the center and spring loaded to assist in closing. They can be used for most media and possess good flow capacity. Sizes range from 2 inches to 60 inches and larger. Because of their design, dual plate check valves are lightweight and have compact face-to-face dimensions. As with butterfly valves, the compact design of dual plate types can require less support and shrink the needed size for a mechanical room. Dual plate valves are available in various body styles that include wafer, lug, and flange; some meet the popular API 594 face-to-face dimensions. Dual plate valves require removal from the line to perform inspection or repair.
