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 PRE3 is a pilot operated pressure control proportional valve, CETOP 03, with mounting interface in compliance with ISO 4401 (CETOP RP 121H) standards. It is suitable to modulate the pressure in hydraulic circuits. The valve can be controlled directly by a current control supply unit or by an electronic control unit to exploit valve performance to the full. Pressure adjustment can be continuous in proportion to the current supplied to the solenoid. Four pressure control ranges up to 350 bar are available.
