Dynamic Monitoring With Complete Memory: Memory, monitoring, and air flow control functions are
simply integrated into two identical valve elements. Valves lock-out due to asynchronous movement of valve
elements 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 only be accomplished by the integrated electrical (solenoid) reset.
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 in-line lubrication.
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.
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.
Basic Size 12 and 30
Intermediate Pilots: Increases pilot air flow for fast valve response, making it possible to use the same size
solenoids as valve sizes 2, 4 & 8, thereby reducing electrical power requirements for these larger valves.

*Kits include all plumbing required for installation. Pressure Range: 125 psig (8.6 bar) maximum.
Designed to improve equipment performance and reduce the Exponentially Perceived Noise (EPNdB) in the 35–40 dB range.
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 quickly pressurized, and pressure in the inlet,
crossovers, outlet, and timing chambers are quickly
equalized. De-energizing thepilots quicklycauses the
valve elements to return to the ready-to-run position.
Valve De-actuated (ready-to-run): 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.(Air passages shown
out of position and reset adapter omitted for clarity.)

DM2® Series C
Valve Operation & Options
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. Reset
is accomplished by momentarily pressurizing the reset port.
Actuation of the reset piston physically pushes the main valve
elements to their closed position. Inlet air fully pressurizes the
crossovers and holds the inlet poppets on seat. Actuation of
the reset piston opens the reset poppet, thereby, immediately
exhausting pilot supply air, thus, preventing valve operation
during reset (Resetadapter added toillustration.). De-actuation
of reset pistons causes the reset poppets to close and pilot
supply to fully pressurize. Reset pressure can be applied by a remote 3/2 normally
closed valve, or from an optional 3/2 normally closed solenoid mounted on the reset
adapter. De-actuation of reset pistons causes the reset poppets to close and pilot
supply to fully pressurize.Reset air pressure can be applied by a remote 3/2 normally
closed valve, or from an optional 3/2 normally closed solenoid, or a manual push
button mounted on the reset adapter.
Status Indicator: The status indicator
pressure switch will actuate when the main
valve is operatingnormally, andwill 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.
Basic Size 12 and 30 valves require relatively large
pilots to actuate and de-actuate the main valve
elements. In order to achieve extremely quick valve
response for such large pilots, a 2-stage solenoid
pilot system is incorporated into the design. This
keeps the required electrical current to operate
the pilots to a minimum.
Status indicator in normal
ready-to-run position.

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)

Some customers prefer to monitor downstream
pressure in addition to using the DM2® or DM1Series
valve. A convenient way to 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).

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
[with the exception of all Filters, Regulators and Lubricators (“FRLs”) which are
warranted for a period of seven years] from the date of purchase to be free of
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 LIABLE TO
PURCHASER, USER, THEIR EMPLOYEES OR OTHERS FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES WHICH MAY RESULT
FROM A BREACH OF THE WARRANTY DESCRIBED ABOVE OR THE USE OR MISUSE OF THE PRODUCTS. NO STATEMENT OF
ANY REPRESENTATIVE OR EMPLOYEE OF ROSS MAY EXTEND THE LIABILITY OF ROSS AS SET FORTH HEREIN.
