The Feed-Valve Pipe

insures that the excess-pressure governor head will regulate the brake-pipe pressure in release position (as the brake-pipe and main-reservoir pressures are then in direct connection through the rotary valve), even though the feed valve is leaking, if not enough to be otherwise detrimental.



The C-6 REDUCING VALVE illustrated in Fig. 44 is used to regulate the pressure that is supplied to the INDEPENDENT BRAKE-VALVE and the AIR-SIGNAL SYSTEM;

it is practically the same as the feed valve just described, but without the duplex adjusting feature, being designed to reduce main-reservoir pressure to a single fixed pressure, which in this equipment is, as already stated,

The C-6 Reducing Valve

45 pounds. It is, in fact, the well-known feed valve that has been used for many years in connection with the G-6 brake-valve, the only distinction being in the name; but, as here used, it is attached to a pipe bracket in the same manner as the B-6 valve. To adjust this valve, remove the cap nut on the end of the spring box; this will expose the adjusting nut by which the adjustment is effected.

The pipe bracket upon which the C-6 Reducing Valve is mounted is the same as is used with the B-6 feed valve--the crossed-passage bracket, in the No. 6 equipment, and the valve turned down in its proper position.
