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 PRE*J valves are pilot operated pressure relief proportional valves with integrated electronics and mounting interface in compliance with ISO 6264 standards (CETOP RP 121H). These valves are normally used to control hydraulic circuit pressure and enable the use of the full flow rate of the pump, even with settings approaching calibrated values. The two-stage design and wide passages ensure reduced pressure drops thereby improving the system energy performance. Pressure can be modulated continuously in proportion to the reference signal.
The valve is controlled directly by an integrated digital amplifier. They are fitted with a manual pressure relief valve which is factory set to ≥15% of the maximum value in the pressure control range. They are available in three sizes for flow rates up to 500 l/min and in three pressure control ranges up to 350 bar.
