Port Threads
Ports of valves and bases described in this catalog have NPT (ANSI
B2.1) threads. Other thread types can be specified by putting an
appropriate prefix letter on the model or part number when ordering.
Flow Ratings
Flow ratings are expressed as CVwhere CV= 1 corresponds to a
steady state air flow of approximately 32 scfm under the following
conditions:
Inlet pressure = 100 psig (6.7 bar)
Pressure drop = 10 psi (0.69 bar)
Air temperature = 68°F (20°C)
Relative humidity = 36%
Note: Because widely differing test standards are used to measure CV
values, the figures given in this catalog should not be used to compare
ROSS valves with those of other makers. The CVratings given here
are intended only for use with performance charts published by ROSS.
The CVratings are averages for the various flow paths through the
valve and are for steady flow conditions.
Approvals and Certifications
ROSSproducts aredesigned tomeet a numberof industrialstandards,
including the Canadian Standards Association (C.S.A.) guidelines.
For more information on specific product approvals, contact your local
distributor or ROSS.
Solenoids
All ROSS standard solenoids are rated for continuous duty (unless
noted otherwise) and will operate the valve within the air pressure
range specified in this catalog.
Explosion-Proof Solenoid Pilot available, for more information
consult ROSS.
Voltage & Hertz
When ordering a solenoid valve, also specify the desired solenoid
voltage and hertz.
Recommended Solenoid Voltages: 100-110 volts AC, 50 Hz;
100-120 volts AC, 60 Hz; 24 volts DC; 110 volts DC.
In addition, the following voltages are available:

CAUTIONS, WARNINGS and STANDARD WARRANTY
PRE-INSTALLATION or SERVICE
1. Before servicing a valve or other pneumatic component, be
sure that all sources of energy are turned off, the entire pneumatic
system is shut off and exhausted, and all power sources are locked
out (ref: OSHA 1910.147, EN 1037).
2. All ROSS products, including service kits and parts, should
be installed and/or serviced only by persons having training and
experience with pneumatic equipment. Because any installation
can be tampered with or need servicing after installation, persons
responsible for the safety of others or the care of equipment
must check every installation on a regular basis and perform all
necessary maintenance.
3. All applicable instructions should be read and complied with
before using any fluid power system in order to prevent harm to
persons or equipment. In addition, overhauled or serviced valves
must be functionally tested prior to installation and use. If you have
any questions, call your nearest ROSS location listed on the cover
of this document.
4. Each ROSS product should be used within its specification
limits. In addition, use only ROSS parts to repair ROSS products.
WARNING: Failure to follow these directions can adversely
affect the performance of the product or result
in the potential for human injury or damage to
property.
FILTRATION and LUBRICATION
5. Dirt, scale, moisture, etc. are present in virtually every air system.
Although some valves are more tolerant of these contaminants than
others, best performance will be realized if a filter is installed to
clean the air supply, thus preventing contaminants from interfering
with the proper performance of the equipment. ROSS recommends
a filter with a 5-micron rating for normal applications.
6. All standard ROSS filters and lubricators with polycarbonate
plastic bowls are designed for compressed air applications only.
Do not fail to use the metal bowl guard, where provided, to
minimize danger from high pressure fragmentation in the event of
bowl failure. Do not expose these products to certain fluids, such
as alcohol or liquefied petroleum gas, as they can cause bowls to
rupture, creating a combustible condition, hazardous leakage, and
the potential for human injury or damage to property. Immediately
replace a crazed, cracked, or deteriorated bowl. When bowl gets
dirty, replace it or wipe it with a clean dry cloth.
7. Only use lubricants which are compatible with materials
used in the valves and other components in the system.
Normally, compatible lubricants are petroleum based oils with
oxidation inhibitors, an aniline point between 180°F (82°C) and
220°F (104°C), and an ISO 32, or lighter, viscosity. Avoid oils
with phosphate type additives which can harm polyurethane
components, potentially leading to valve failure which risks human
injury, and/or damage to property.
AVOID INTAKE/EXHAUST RESTRICTION
8. Do not restrict the air flow in the supply line. To do so could
reduce the pressure of the supply air below the minimum
requirements for the valve and thereby cause erratic action.
9. Do not restrict a valve’s exhaust port as this can adversely
affect its operation. Exhaust silencers must be resistant to clogging
and must have flow capacities at least as great as the exhaust
capacities of the valves. Contamination of the silencer can result
in reduced flow and increased back pressure.
WARNING: ROSS expressly disclaims all warranties and
responsibility for any unsatisfactory performance
or injuries caused by the use of the wrong type,
wrong size, or an inadequately maintained silencer
installed with a ROSS product.
POWER PRESSES
10. Mechanical power presses and other potentially hazardous
machinery using a pneumatically controlled clutch and brake
mechanism must use a press control double valve with a monitoring
device. A double valve without a self-contained monitoring device
should be used only in conjunction with a control system which
assures monitoring of the valve. All double valve installations
involving hazardous applications should incorporate a monitoring
system which inhibits further operation of the valve and machine in
the event of a failure within the valve mechanism.
ENERGY ISOLATION/EMERGENCY STOP
11. Per specifications and regulations, ROSS L-O-X® and L-O-X®
with EEZ-ON® operation products are defined as energy isolation
devices, NOT AS EMERGENCY STOP DEVICES.
All products sold by ROSS CONTROLS are warranted for a one-year period
[withthe exceptionof allFilters,Regulators and Lubricators(“FRLs”) which are

defects in material and workmanship.ROSS’obligation under this warranty is
limited to repair or replacement of the product or refund of the purchase price paid solely at the discretion of ROSS and provided
such product is returned to ROSS freight prepaid and upon examination by ROSS is found to be defective.This warranty becomes
void in the event that product has been subject to misuse, misapplication, improper maintenance, modification or tampering.
THE WARRANTY EXPRESSED ABOVE IS IN LIEU OF AND EXCLUSIVE OF ALL OTHER WARRANTIES AND ROSS EXPRESSLY
DISCLAIMS ALL OTHER WARRANTIES EITHER EXPRESSED OR IMPLIED WITH RESPECT TO MERCHANTABILITY OR FITNESS
FOR A PARTICULAR PURPOSE. ROSS MAKES NO WARRANTY WITH RESPECT TO ITS PRODUCTS MEETING THE PROVISIONS
OF ANY GOVERNMENTAL OCCUPATIONAL SAFETY AND/OR HEALTH LAWS OR REGULATIONS.IN NO EVENT IS ROSS LIABLETO
