Dynamic Monitoring: Monitoring and air flow control functions are integrated into two identical valve
elements for CAT 4 applications. The valve exhausts downstream air if asynchronous movement of
valve elements occurs during actuation or de-actuation, resulting in a residual outlet pressure of less
than 1% of supply. If the abnormality clears itself, the valve will return to the ready-to-run state; there
is no memory of the abnormal behavior, as in the ROSS DM2® Series E and DM2® Series C products
that require an intentional reset following lockout.
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.
Ready-to-run: If an abnormality clears itself upon the removal of electricity to both solenoids, it will be
ready-to-run again. It does not remember the abnormality and stay in a locked-out state until intentionally
reset. Therefore, cumulative abnormalities may go undetected.
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 “ready-
to-run” condition or has experienced abnormal function. MUST be integrated into machine controls in
order to prevent run signal until fault is cleared in valve. This indicator only reports status, it is not part
of a lockout function.
Silencers: All models include high flow, clog resistant silencers.
Mounting: Base mounted – with BSPP or NPT pipe threads. Inlet and outlet ports on both sides
provide for flexible piping (plugs for unused ports included). Captive valve-to-base mounting screws.

Status Indicator:
Thestatusindicatorpressure switch
will actuate when the main valve is
operating normally, and will de-ac-
tuatewhen themain valve operation
is sufficiently asynchronous or inlet
pressure is removed. This device is
notpartofthevalvelockoutfunction,
but, rather, only reports the status
of the main valve.
Asynchronous Operation: If the valve elements operate in a sufficiently asynchronous manner on ACTUATION, the valve
will shift into a position where one crossover and its related timing chambers will be exhausted, and the other crossover and its
related timing chambers will be pressurized.
In the illustration, side B is in the de-actuated position, but has no pilot air available to actuate with and has full pressure on its
upper and lower inlet poppets and return piston to hold it in place.
Inlet air flow on side B into its crossover is restricted and flows through the open upper inlet poppet on side A, 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.
Once the main solenoids are de-energized, actuating pressure is removed from the top of the main pistons and then the lower
inlet poppet return spring along with inlet air pressure acting on the side A return piston will push side A back into the de-actuated
position. Inlet air pressurizes the crossovers and volume chambers. Pressure in the crossovers helps hold the upper inlet poppets
on seat. The valve will then be in the ready-to-run position. On the next attempt to actuate normally, if side B is still unable to
actuate synchronously with side A, the same sequence of events described above will occur again.
Valve actuated: Energizing the pilot solenoids
simultaneouslyapplies pressure to bothpistons,
forcingtheinternal partstomovetotheiractuated
position,whereinletairflowto outlet is open and
both exhaust poppets are closed. The outlet is
then quickly pressurized, and pressure in the
inlet, crossovers, outlet, and timing chambers
are quickly equalized. De-energizing the main
solenoids causes the valve elements to return
to the ready-to-run (de-actuated) position.
Valve de-actuated (ready-to-run): The flow of inlet
air pressure into the crossover passages from the inlet
chamber is restricted by orifices that allow air pressure to
bypass the lower inlet poppets. Flow is sufficient to quickly
pressurize the pilot supply/timing chambers on both sides
A and B. The upper inlet poppets prevent air flow from the
crossover passages into the outlet chamber. Air pressure
acting onthe inlet poppetsand return pistons securelyhold
the valve elementsin the de-actuatedposition. (Internal air
passages shown out of the valve body for clarity.)
Status indicator
in normal
ready-to-run
position
WARNING: If asynchronous operation occurs while DE-ACTUATING,
the pilot supply/timing chambers on one side will still be exhausted as
described above. However, this could be a temporary situation because
the cause of the asynchronous operation may be able to correct itself
allowing the stuck or slow acting side of the valve to eventually move
back into the de-actuated position. Once the slow or stuck side has
de-actuated, the pilot supply/timing chambers that were exhausted will
then repressurize. If an external monitoring system is only checking
the status indicator periodically this fault signal could be missed. The
machine’s safety system must be designed to ensure that this does
not cause a hazardous situation.

Some customers prefer to monitor downstream
pressure in addition to using the DM2® or DM1Series
valve. Aconvenientwayto do this is to install a pressure
switch in the extra outlet port that is provided on the
valve. The Outlet Port Pressure Monitoring kit can be
used with one of the J-Box kits above to split one of the M12 ports on the J-Box so that a pressure switch
can be wired in as well. These kits consist of one port splitter (a Tee with three M12 connectors) and one
M12-DIN cable (1 meter).

Wiring Kits with J-Box
A J-Box is a junction box with a 10-pin MINI connector for connecting to the user’s control system
and (4) 5-pin M12 ports for connecting to the 3 solenoids and the status indicator on the DM2®
Series valve. The J-Box kits include the J-Box as described above and (4) 1-meter cables for
connecting to the valve. These cables have a connector on each end. The status indicator
cable and the (3) solenoid cables have an M12 connector on one end and a EN connector on
the other end (M12-DIN).
Standard valves come with DIN type
solenoid connections, but could be
bought with M12 type connections as
well. Therefore we also offer a kit that
provides solenoid cables with an M12
connector on each end (M12-M12). 3.9 (100)

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.
