Abstract:
A check valve for a backflow prevention assembly includes a linkage with a platform having a proximal end and a distal end and a first coupling member supported by the platform for engaging a bias assembly. A stop protrudes from the proximal end of the platform to engage a frame of the check valve for limiting travel of the platform. A branch depends from the proximal end of the platform, the branch having a hinge pin configured to nest in a slot defined by check valve. A second coupling member depends from the distal end of the platform for engaging a valve member.
