The new release of Atos website is already running on and contains updated
NEWS page and catalog on-line plus additional marketing tools and information.
Moreover, the new KT12-0/E paper master catalogue in English version has been recently
printed: it includes several updated technical tables and new components, and it is available
on request. Interesting news: DHE(R) directional valves, AES digital driver with improved
features, AEG and AEZ cycle generators and -TEZ, Z-ME-KZ axis controllers. The catalog
has been integrated with specific information about compatibility of valve’s drivers, electronics

• Availability of new DHE(R), DP2, DP-3 directional valves
The new solenoid valves DHE and DHER are already available for pre-series supply; the
serial production is forecasted starting from June. DP-2 with new body casting are also
immediately available for pre-series, while the series is expected starting from May. DP-3 are
still in prototyping phase. The pre-series will be available around June/July and the series
from September.
Technical documentation: tech. tables E015 (DHE and DHER) and E085 (DPH*-2 and -3)
available in Atos on-line catalog & KT12
Prices: already included in 2012 Price list
• ISO 7790 standard for clamping dimensions
In reference to the new issue of standard ISO 7790 defining the installation dimensions of
fixing bolts for directional valves, we confirm you that DHE, DHER, DKE, DKER, DP-1, and
the new execution of DP-2, DP-3 and DP-6 are in compliance with the specification
requirements. DHI and DHU cannot be modified due to technical reasons, so they cannot be
aligned to the new ISO standard.

• News about ex-proof valves
IECEx international certification for ex-proof integral electronics
The worldwide recognized certification IECEx has now been extended to ex-proof proportional
valves with integral digital electronics. In the next step the IECEx certification will be introduced
also for the ex-proof proportional valves for mining.
Technical documentation: tech. table F600 available in Atos on-line catalog & KT12
Availability: running
Prices: already included in 2012 Price list
DHA with ex-proof proximity sensor
Ex-proof directional solenoid valve code 042124 DHA, equipped with ex-proof proximity
sensor for spool position detection, has been developed for safety applications in oil & gas
and potential hazardous areas. The valve is certified according to ATEX Ex II 2GD Ex d IIC
T6/T4/T3 and it is available in selected configurations.
Technical documentation: tech. table TE120 will be available in new issue of TAK12 on line &

Ex-proof solenoids with suppressor diode
The directional ex-proof solenoid valves type DHA are available in special execution 002290
DHA-** with a suppressor diode installed inside the solenoid to eliminate the electric
disturbances at the valve de-energizing.
This version is certified according to ATEX Ex II 2GD Ex d IIC T6/T4/T3 and it is available with
all configurations and spools provided by the standard DHA range.

• Hand lever valves for marine application (Winch control)
Special hand lever valves designed for winch controls in marine applications.
Thanks to the spool shape derived from proportional execution and to the wide lever working
stroke, they permit a fine and sensible control of the regulated flow.
These valves are also predisposed to be remotely operated through ports X and Y by means
of a proportional pressure reducing valve, operating in the range 0 to 20 bar.
This special version is available in ISO size 10, 16 and 25

• Proportional relief valves with pressure regulation up to 500 bar
The proportional pressure relief valve type RZMO-A*-010/500 controls the pressure in the range
from 30 to 500 bar and it is designed for mobile sector and high tons presses in which the high
working pressure permits a significant reduction of weights, dimensions and costs of the
machinery. It is available without (-A) or with integral analogue (-AE) or digital (-AES) electronics

• Proportional valves with command signal +/- 10mA
The proportional directional valves type 040261 DHZO, DKZOR and DPZO are equipped with
special integral analogue electronics -AE, -TE, -LE suitable to receive command signal +/- 10
mA ( instead of 4-20 mA of standard option /I).
They have been developed to permit the electrical interchangeability with Moog and Parker
valves. We remind you that for standard digital integral drivers with option /I, the current
command signal is software selectable by the end user in any value within the range +/-20 mA

• New climatic chamber for temperature and humidity tests
The environmental test s are of primary importance to verify the components resistance to
particulars ambient conditions. At this purpose a climatic test chamber has been recently
purchased by Atos to verify the resistance of components like solenoid coils, integral
electronics and transducers to high humidity conditions and strong temperature excursion.
This new instrument, in addition to the already existing facilities for thermal, salt fog, vibration/
shock and rain tests, improves the capability to verify the behavior of complete valves and
single parts when exposed to heavy environmental conditions in order to improve the overall
component’s quality and performances.

• Instrumentation for contamination level control
Improved component’s cleaning project
The project for the improvement of the whole production cycle according to ISO16232 (see
INFOTEC Valves n.14) is quickly proceeding with the recent introduction of new specific
equipments for the contamination control. These instruments (filtering cabinet, microscope
and gravimetric balance) permit to verify the cleanliness degree of the valve’s components
during all phases of the production cycle and then through the constant monitoring of the
complete cycle, ensure high cleanliness standards.
New test equipment for contamination control
New portable particles laser counter performs the real time analysis of the fluid contamination
level according to ISO4406, NAS1638 and SAE4059 standards. This instrumentation permits
to Atos service personnel to verify the contamination degree of the fluid present in customer’s
systems and providing them a useful support to identify the actions to improve the efficiency
of their fluid cleaning equipments. The portable laser counter can be used both with mineral
oils and phosphate esters fluids.
