A dual plate wafer check valve closes two half-discs on a central hinge pin, reaches about one quarter the face-to-face length of a swing check valve, and shuts in under 0.3 seconds. This guide covers the API 594 retainerless design, seven selection parameters, and the J-VALVES range from DN50 to DN1200 in Class 150 through 2500.
