1. A valve, comprising:
- at least one of an electrical port adapted to receive an electronic control signal and a pneumatic control port adapted to receive a pneumatic control signal; and
a pneumatic delivery port adapted to transmit a pneumatic fluid, based on at least one of the received electronic control signal and the received pneumatic control signal, from a second independent source to control i) a second associated service brake and ii) delivery of the pneumatic fluid from a first independent source to control a first associated service brake.

Abstract
A valve includes at least one of an electrical port adapted to receive an electronic control signal and a pneumatic control port adapted to receive a pneumatic control signal. The valve also includes a pneumatic delivery port. The pneumatic delivery port is adapted to transmit a pneumatic fluid, based on the at least one of the received electronic control signal and the received pneumatic control signal, from a second independent source to control i) a second associated service brake and ii) delivery of the pneumatic fluid from a first independent source to control a first associated service brake.
