Subject: 

The MV-2 Control Valve has been released and is being used at the present time by
White and I.H.C. on certain models.  This is a modular-type control valve with two
buttons, which will perform the following functions:

•  Tractor protection control

•  Trailer service air supply

• System 

park

•  Trailer park only

•  Trailer charge with tractor spring brakes applied (tractor park only)

•  Supplied reservoir selection

The valve will be serviced by spool replacement cartridges and a dual circuit supply
valve maintenance kit.

The service spool for the trailer control portion (red button) is 101569.  This includes a
pre-lubricated spool and a spirol pin for attaching the button.

The spool for tractor control (yellow button) is piece No. 101570; also packaged pre-
lubricated with spirol pin included.

The dual circuit supply valve, included in the tractor control section, is a spring loaded
valve which selects No. 1 reservoir as the supply for both control valves, unless No. 1
reservoir falls at least 25 p.s.i. below No. 2 reservoir, at which point the valve will cycle
and establish No. 2 reservoir as the supply.  Dual circuit supply valve may be serviced
with a maintenance kit Piece No. 101557.

Note: Reservoir No. 1 must be the reservoir that supplies the rear tractor

axle(s).

Reservoir No. 2 must be the reservoir that supplies the front axle.
