Check valve assembly for full-power brake systems is a compact manifold assembly that includes a check valve and inverted shuttle valve. It supplies fluid for two separate accumulator circuits while reducing the necessary number of system components and plumbing and hardware requirements. It features high flow capacity to 11 gpm and maximum operating pressure of 3625 psi. It reduces potential leakage and failure points, limiting leakage to a maximum of 0.25 cm/min 3
at 3500 psi.
