Abstract
A hydraulic valve module () for a vehicle () is configured to receive hydraulic pressure from a first pump () via a first pump inlet () in a first interface surface when connected to a first adjacent module (), and from a second pump () via an external port (). The module () combines both flows to supply a work function circuit () of a vehicle via a port () formed in a second interface surface to communicate with a second adjacent module (). The module () prioritises flow from the second pump () to a steering circuit () over the work function circuit, and restricts flow from the first pump () to the work function circuit to prioritise and maintain pressure in the first adjacent module upstream of the first pump inlet () which may supply service brake and cooling fan circuits () of the vehicle.
