ELECTRICAL CONNECTORS
Electrical connections to the valves can be made with sealed 4 or 5-pin
connectors (ANSI Standard B93.55) or by conventional hard wiring.
Sealed Connector. A 4 or 5-pin straight connector wired as required
by either the Ford Motor Company or the Chrysler Corporation
is available. Valves may be ordered with mini- or micro-change
connectors. See the wiring diagrams below for the various options
available.

Single Control. 5-port, 2-position (5/2) valves that require a main-
tained signal to keep the valve in its shifted position. Internal air
pressure provides the force to return the valve when the signal is
removed.
Poppets are face sealing valve elements which can open or close
passageways without sliding friction or the close tolerances required
of spool valves. Poppets don't build up breakaway resistance due
to varnish, and are highly tolerant of dirty air.
ROSS poppet valves have rugged internals and self-adjusting
exhaust poppet seats which equalize wear and promote long life.
Designed for use with or without air line lubrication.

Poppet Valve Construction
Double Control. 5-port, 2-position (5/2) valves that require only a
momentary signal to shift the valve in either direction. A mechanical
detent and differential air pressure keep the valve in its shifted
postion.
The SAE Standard Interface, though originally developed by
U.S. auto companies in the early 1970s, has quickly gained wide
acceptance throughout the industry. Due to the design's ruggedness
and high-flow characteristics, the Society of Automotive Engineers
(SAE) established it as a new standard. This ensures that valves
designed to fit the SAE interface will be interchangeable, regardless
of manufacturer. In practical terms, the user can change from
one brand of valve to another without changing installed bases or
manifolds.
ROSS valves are available in SAE sizes 125, 250 and 500. Both
poppet and metal spool-and-sleeve construction are offered. The
valves described in this bulletin are all solenoid-pilot controlled.
SOLENOID PILOTS
Internal or External Pilot Supply. Valves in this bulletin are made
for internal pilot supply. However, they are easily converted for use
with an external pilot supply by moving a single pipe plug in the
bottom of the valve.
With solenoid pilot control, the main valve is shifted by applying air
pressure to an actuating piston or spool end. There is no mechanical
connection between the solenoid plunger in the pilot and the main
valve mechanism as there is in a valve actuated by a direct-acting
solenoid. If the valve mechanism were to stick, the plunger in a
solenoid-pilot-controlled valve could complete its travel and avoid
the high current flow which results when the travel is incomplete.
Thus overheating and solenoid burnout are avoided. Furthermore,
under average shop conditions, air pressure produces a valve-shifting
force much greater than that from a direct-acting solenoid, so that
the problem of valve sticking is minimized.
Indicator Lights. An indicator light is wired to each solenoid
circuit so that the light is illuminated whenever the solenoid is
energized.
Hard Wiring. An electrical opening, threaded 1/2 NPSC, is available
for use with conventional fittings.
