A supply valve for use in a vehicular braking system includes a housing. A sleeve is disposed within a bore in the housing. A piston is slidably disposed within the bore. A valve element is disposed within the sleeve and includes a valve seat and check element for sealing against the valve seat to close the valve element. A lip seal is disposed on the sleeve for allowing fluid to flow from a low pressure accumulator to a pump, but not in the opposite direction. The supply valve is particularly adapted for use in an anti-lock braking system equipped with traction control.
