I had a problem with my electronic brake valve getting it to reprogram after I switched over to 2.4. I am not sure of what king it is.
It is the tall black plastic one with the set button on the side. It looks a little like the Orbit. I went to thier Web site and down loaded thier instruction and now it workes perfectly. Here is the link and programing steps.

Programming:
The Orbit PRO-Single-Action-Valve can be operated either in switching mode for cylinders
with return spring (e.g. Eurokit, Spring-Air) or in a proportional mode for air pressure brakes.
To toggle between these modes, hold the SET-button pressed while turning on the R/C
system. The status LED confirms the successful switchover.
● Pressing the SET-button for 1-2 seconds teaches the valve OFF (2: => 3
.
The status LED confirms this by flashing.
● Pressing the SET-button for more than 5 seconds teaches the valve ON (1: => 2
.
The status LED confirms this by flashing.
● Now the valve should follow the control input from the R/C transmitter.
Switching mode: The status LED shows valve ON (retract landing gear) or valve
OFF (extend landing gear).
Proportional mode: The valve pulses proportionally to the control input from 0 % to
100 %. Pressing the SET-button for 3 seconds stores the current R/C position (e.g.
elevator) as valve OFF OFFSET. The status LED confirms this by flashing. This
allows the input range to be spread to the best braking effect.
