ISO Base Mounted
Valves |

ISO valve-to-base interface standards are
internationally recognized and used throughout the world. Valves made for
bases conforming to ISO standards are interchangeable without regard to
manufacturer. ROSS offers a full line of base-mount valves that conform to
the ISO valve-to-base mounting interface standard which specifies the “foot
print" of the valve - indicating size and locations of ports, mounting
bolts, and maximum valve width.

Series W60 Metal
Spool & Sleeve
The matched spool and sleeve are precision finished, hardened, stainless
steel. The spool moves on a micro-inch film of air between spool and sleeve
so that wear is minimized. Designed for use in systems with or without air
line lubrication. Available in both 2-position and 3-position designs.

Series W60 Energy
Saver
Traditionally,
standard valves apply the same pressure for extending and retracting
double acting cylinders. This EnergySaver valve revolutionizes the way
cylinders are controlled by reducing the cylinder retract pressure.

Poppet Construction
Poppets are face seals which can open or close
passage ways without sliding friction or the close tolerances required of
spool valves. They don’t build up breakaway resistance due to varnish, and
they 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.

SAE Base Mounted
Valves |
|
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. |

Vacuum Service
In vacuum
service applications, the pressure within the valve is reduced below
atmospheric pressure. Consequently, atmospheric pressure actually pushes air
into the valve, instead of the common belief that air is “sucked” in by the
vacuum.

Double
Valves & Press Solutions |
|
ROSS Double Valves, also known as “Control-Reliable valves"," Safety
valves”, “Press valves”, “SERPAR® valves”, “Crossflow® valves”, and the
“Critical Application Valve”, are pneumatic or hydraulic control valves with
two valve elements (redundant or dual channel), both of which must operate
in order to supply pressure to the outlet port of the valve. The general
function of these valves is that of a 3/2 normally closed valve (except for
the 5/2 CROSSMIRROR®). The main difference between these widely known double
valves and standard solenoid valves, though, is that any condition, which
might cause one valve element to not shift along with the other, results in
no output to the work device. The outlet port, in this situation, is
connected to exhaust and the supply inlet is closed. |

CROSSMIRROR®
Series-77 3/2 & 5/2 Double Valves
The patented CROSSMIRROR® dynamic monitoring
system and dual valve design combine to handle the most stringent of
safety-related applications for pneumatic equipment – Category 4
safety-related applications. The internal dynamic monitor checks the valve
on each cycle and includes an automatic lock-out function to inhibit further
operation of the valve. The CROSSMIRROR® is available with remote reset or
integrated solenoid reset. Both reset types are “tamper-proof” and the valve
cannot be reset while the main valve solenoids are energized. Also, the
reset function cannot be over-ridden by removing and reapplying the valve's
electrical or pneumatic energy sources. Removing the inlet air supply causes
the valve to lock-out, and, therefore, the valve must be reset after the air
supply is reapplied.

SERPAR®
Crossflow Series-35 Double Valves
The design of the SERPAR® Crossflow double valve
is distinguished by crossflow passages and spool valving on the main valve
stems. This arrangement provides the valve's unique flow characteristics.
Self-contained monitors, designed to inhibit valve operation in case of a
fault within the valve, are built into the valve assemblies of sizes 4, 8,
12, and 30 valves. There are three types of ROSS monitors available:
pneumatic (L-G), electro-pneumatic (E-P), and electronic (D-S). Crossflow
valves are also available with pressure switches for incorporation into
press control systems with external monitors.

Flow Control
Valves
Flow control valves are used to control air flow
from air cylinders, thereby controlling the speeds at which the pistons in
the cylinders move. They allow free flow in one direction and adjustable,
precision controlled flow in the other direction. Right angle flow control
valves function like those described above. However, their compact right
angle design permits use where conventional straight-through flow controls
might be undesirable.
|
 |
Shuttle
Valves
ROSS shuttle valves have two inlets and one
outlet. The first inlet to be pressurized is connected to the outlet, and
the second inlet is then closed. Thus, a pneumatic device connected to the
shuttle outlet can be operated by either of two control valves connected to
the shuttle inlets. |
|
 |
Quick Exhaust Valves
Quick cylinder reversal can be a problem if the
control valve is at a distance from the cylinder or otherwise restricts the
exhaust fl ow. A ROSS quick exhaust valve near the cylinder opens as soon
as the controls valve begins exhausting, and thus allows quick reversal of
the cylinder.
|
 |
Check Valves
ROSS check valves are
self-actuating and designed to provide free air flow in one direction,
and to be closed to flow in the opposite direction. |
|
 |
Pilot-Operated Check Valves w/ Trapped Pressure Relief
Pilot operated check valves with trapped pressure relief can be used to
control vertically mounted pneumatic cylinders in the following ways:
Maintaining a vertical cylinder in a stationary position, even upon loss of
electrical power.
Jogging a vertical cylinder.
Relieving pressure trapped between check valve and cylinder.
|
 |
Right-Angle Pilot Operated Check Valves
Pilot Operated Check Valves
are used to block the return of air from cylinders or other devices.
Air flows freely from port 1 to port 2, but a signal at port 12 is
required to allow flow in the reverse direction from port 2 to port 1.
Right-angle models with threaded Banjo are designed for easy
positioning of pipe or tubing.
|
|
 |
Pilot-Operated
Check Valves
Pilot-Operated Check Valves are used to block the
return of air from cylinders or other devices. Air flows freely from port 1
to port 2, but a signal at port 12 is required to allow flow in the reverse
direction from port 2 to port 1. Can be used wherever a high-flow or
remotely-controlled checking function is needed. Can be used in a circuit to
provide automatic stopping of a cylinder in the event of the loss of
electrical or pneumatic power. Also available with an Automatic exhausting
function, Remote and Manual Trapped Pressure Relief Function, or Solenoid
Pilot Dual P.O. Check. Available in the following variations:
