Description
DESCRIPTION The PRE*J, PRE*JL PRE*JH, are proportional pressure relief valves, pilot operated, with integrated electronics and feedback for closed loop of pressure. They are used to modulate the pressure of the hydraulic circuit and allow the use of the entire flow of the pump, even with pressure values near the set value. They are fitted with a pressure relief valve. The calibration is performed within the Duplomatic Company at the value of ≥ 15% of the maximum pressure value in the adjustment range. They are available in three different sizes for flow rates up to 500 l/min and in three pressure regulation ranges up to 350 bar. On-Board Electronics Options for pressure closed loop: J Version: Standard electronics with an analogue interface, with current or voltage reference signal, and a 6-pin + PE connection. Ideal for traditional applications with direct control. JL Version: Compact and cost-effective electronics with Io-Link, Can-Open, or analog interface and a 5-pin M12 connection. Perfect for applications requiring advanced connectivity. JH Version: Supports fieldbus communication with EtherCAT, Ethernet/IP, and Profinet interfaces, using an 11-pin M12 connection. Optimal for advanced industrial applications with complex communication needs.
