Valve Wiring
Dynamic Monitoring With Memory: Memory, monitoring, and air flow control functions are integrated into
two identical valve elements. Valves lock-out if asynchronous movement of valve elements occurs during
actuation or de-actuation, resulting in a residual outlet pressure of less than 1% of supply.
An Action is Required for Reset: Cannot be reset by removing and re-applying supply pressure. Reset
can be accomplished by the integrated electrical (solenoid) reset or by the manual reset button.
Basic 3/2 Normally Closed Valve Function: Dirt tolerant, wear compensating poppet design for quick
response and high flow capacity. PTFE back-up rings on pistons to enhance valve endurance – operates
with or without inline lubrication.
LED Indication: Light-emitting diode (LED) indicators of main solenoid operation, reset solenoid operation,
and status indicator condition.
Status Indicator: Includes a pressure switch with both normally open (NO) and normally closed (NC)
contacts to provide status feedback to the control system indicating whether the valve is in the lockout or
ready-to-run condition.
Transducer (optional): For monitoring of downstream pressure in the system.
Silencers: All models include high flow, clog resistant silencers.

Status Indicator:
The status indicator pressure switch will actuate when the
main valve is operating normally, and will de-actuate when
the main valve is in the locked-out position or inlet pressure is
removed. This device is not part of the valve lockout function,
but, rather, only reports the status of the main valve. If the
valve is in a ready-to-run condition, a green “STATUS” LED
will be displayed. If the valve is faulted or there is no air
pressure at the inlet, a red “STATUS” LED will be displayed.
Resetting the valve: The valve will remain in the locked-out position, even if the inlet air
supply is removed and re-applied.
A remote reset signal must be applied to reset the valve. A momentary, remote electrical
signal must be applied to the reset solenoid to apply pressure to the reset pistons in the valve.
Actuationoftheresetpistonphysicallypushesthe mainvalve elementsto theirclosedposition.
Inlet air fully pressurizes the crossovers and holds
the inlet poppets on seat. Actuation of the reset
pistonopenstheresetpoppet,thereby,immediately
exhausting pilot supply air, thus, preventing valve
operation during reset (Reset adapter added to
illustration.). De-actuation of reset pistons causes
the reset poppets to close and pilot supply to fully
pressurize. Reset air pressure is applied by a 3/2
normally closed solenoid, or a manual push button
mountedontheresetadapterinthe top valvecover.
A green“RESET SOL.” LED will be displayed when
the reset solenoid is energized.
The reset procedure is as follows:
•Remove the electrical signals to the main coils
•Ensure there is air supplied to the valve
•Energize the reset solenoid for a minimum of 200 ms
• Allow a 200 ms delay after de-energizing the reset solenoid and re-energizing the main
solenoids
Valve locked-out: Whenever the valve elements operate in a sufficiently asynchronous manner, either on
actuation or de-actuation, the valve will move to a locked-out position. In the locked-out position, one crossover
and its related timing chamber will be exhausted, and the other crossover and its related timing chamber will be
fully pressurized. The valve element (side B) that is partially actuated has pilot air available to fully actuate it, but
no air pressure on the return piston to fully de-actuate the valve element.
Air pressure in the crossover acts on the differential of side B stem diameters creating a latching force. Side A is in
a fully closed position, and has no pilot air available to actuate, but has full pressure on the inlet poppet and return
piston to hold the element in the fully closed position. Inlet air flow on side A into its crossover is restricted, and
flows through the open inlet poppet on side B, through the outlet into the exhaust port, and from the exhaust port
to atmosphere. Residual pressure in the outlet is less than 1% of inlet pressure. The return springs are limited in
travel, and can only return the valve elements to the intermediate (locked-out) position. Sufficient air pressure acting
on the return pistons is needed to return the valve elements to a fully closed position.
Valve actuated: Energizing the pilot valves simultaneously applies
pressure to both pistons, forcing the internal parts to move to their
actuated (open) position, where inlet air flow to crossover passages is
fully open, inlet poppets are fully open and exhaust poppets are fully closed. The outlet is then pressurized at
a rate allowed by the fixed orifice and the adjusted flow control. Once the air pressure in the outlet chamber
reaches approximately 60% of inlet pressure, the air piloted 2-way normally closed poppet valve opens fully
and the pressure in the inlet, crossovers, outlet, and timing chambers are quickly equalized. The adjustable
flow control will control the time it takes for the outlet air pressure to reach approximately 60% of inlet pressure.
Green “SOL. 1” and SOL. 2” LEDs will be displayed when the main solenoids are energized.
De-energizing the pilots quickly causes the valve elements to return to the ready-to-run position.

Valve de-actuated (ready-to-run): The flow of inlet air pressure to the inlet chamber of the main valve
internals is restricted by a fixed orifice and an adjustable flow control as well as an air piloted 2-way normally
closed poppet valve. The flow of inlet air pressure into the crossover passages is restricted by the size of
the passage between the stem and the valve body opening. Flow is sufficient to quickly pressurize pilot
supply/timing chambers A and B. The inlet poppets prevent air flow from crossover passages into the outlet
chamber. Air pressure acting on the inlet poppets and return pistons securely hold the valve elements in
the closed position. (Reset adapter omitted for clarity.)

For order placement, consult ROSS or your local ROSS distributor.
For a current list of countries and local distributors, visit ROSS’ website at www.rosscontrols.com.
Standard Specifications
The standard specifications for the products on each page of this
catalog are given on the same page or referenced. For solenoid pilot
valves, models with internal pilot supply are listed. Most models are
also available for use with external pilot supply or have a built-in pilot
supply selector valve.
Theproducts inthiscatalog areintended for use inindustrial pneumatic
systems. Mostproducts are adaptable to otheruses andconditions not
covered by the standard specifications given in this catalog. Weights
shown are approximate and are subject to change. Dimensions given,
unless otherwise noted, are envelope dimensions (not for mounting).
Consult ROSS for further information.
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.

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
