Duplomatic DZCE*K – Explosion Proof Pressure Reducing Proportional Valve

~ scroll down to find the part you need ~
Duplomatic Oleodinamica designs and produces a complete range of hydraulic components that are suitable for all application sectors of both industrial and mobile fields.

The Duplomatic DZCE*K are explosion-proof pressure reducing proportional valves, pilot operated, in compliance with ATEX 94/9/EC standards. They are suitable for use in potentially explosive atmospheres, that fall within the ATEX II 2GD either for gas or for dust classification and I M2, for mines.

The pressure can be modulated continuously in proportion to the current supplied to the solenoid.

They can be controlled directly by a current control supply unit or by means of an electronic card to exploit valve performance to the full.

They are available with CETOP P05, ISO 4401-05 (CETOP R05), ISO 4401-07 (CETOP 07) and ISO 4401-08 (CETOP 08) mounting surfaces.

The statement of conformity to the up mentioned standards is always supplied with the valve.

Upon request, DZCE*K valves can be supplied with a finishing surface treatment (zinc-nickel) suitable to ensure a salt spray resistance up to 600 h (test operated according to UNI EN ISO 9227 standards and test evaluation operated according to UNI EN ISO 10289 standards).
