Duplomatic Oleodinamica offers a complete range of proportional valves: pressure control, flow control, directional, explosion-proof, high response. The various models are available with or without on-board electronic (OBE), feedback and in closed loop. Along with that, Duplomatic Oleodinamica offers many digital electronic cards to control proportional valves.
Efficiency, speed, accuracy, repeatability and the chance to program the control are only some of the many benefits of introducing proportional technology on electro hydraulics applications. These valves, combined with the increasing potential of advanced electronics are able to address the needs of various application fields fitting each specific reality.
Moreover, electronics allows to speed up the processes while reducing wastes and errors margins. All that to advantage of operative costs that will be reduced.
Since more than 30 years Duplomatic Oleodinamica, designs and produces proportional valves to grant its customers the chance to take full advantage of these benefits. Advanced electronics, state of the art prodcutive processes along with a continuous research and development program make this possible.
The evolution of the markets' needs along with our willingness to serve at best our customers have led us to expand our offer with ex-proof versions and/or with Zinc-Nickel surface treatment.
In the first case we are talking about components compliant with the ATEX 94/9/CE directive. These proportional valves are suitable for the use in environments characterized by a potentially explosive atmosphere belonging to the ATEX II 2GD classification for gases and dusts.
The Zinc-Nickel finishing on the other hand ensures a salt spray resistance up to 600 hours (test performed according to the UNI EN ISO 9227 protocol and test validation done in compliance with the UNI EN ISO 10289 norms).
