A check valve assembly includes a housing having a fluid inlet arranged to be fluidly connected, in use, to a source of hydraulic fluid, a first stage body having a first stage fluid outlet and a second stage body having a second stage fluid outlet and a flow passage between the first and second stage bodies. The first stage body is a hollow body having a first end in fluid communication with the fluid inlet and housing a hollow first stage retainer around which is mounted a first stage spring that biases a first stage ball. The second stage body is a hollow body housing a second stage retainer around which is mounted a second stage spring that biases a second stage ball, and wherein a first stage pressure differential between the first stage fluid outlet and the fluid inlet creates a fluid flow path from the inlet outlet.
