Schematic for 737 Dual Concentric Servo Valve
Anyone got any good schematics of this valve that will help me figure out how it works?
I've found one or two on the WWW but not with enough detail to help me figure the valve out...
Thanks.

Much obliged....although the intricacies of the valve still elude me.

I presume the channels on the top side of the valve concern the other hydraulic system - after all the rudder may be powered by eithered hydraulic system?
I am still bemused as to why two slides are needed?
