No.
The GN combination valve does include a proportioning valve as part of it, thou.
The combination valve, delays, and intially limits the pressure to the rear shoes.

Just follow the lines down from the Master Cylinder. That big junction block is it.

The combi valve is:

The metering valve, proportioning valve, and brake warning lamp switch all in one unit.
