The DDPE*J, DDPE*JL and DDPE*JH are proportional directional valves, pilot operated, with on-board electronics and position feedback, for subplate mounting. Available in sizes from ISO 4401-05 to ISO 4401-10 with oversized ports, they are used to control the position and speed of the hydraulic actuators. Spools with open center and with closed center are available for each size. Special spools are available for DDPE7J, for regenerative circuits made with external check valve. Progressive differential spool specific for alternate p/Q control, typical of plastic injection cycles are also available. The DDPE*J* valves are available with internal or external pilot supply and are always equipped with a 30-bar pressure reducing valve. Drain can be internal or external. The version with external drain allows a higher back pressure on the T line. The valves are available with different types of on-board electronics for closed loop: The J version is our standard electronics with analogue interface with current or voltage reference signal with connection 6 pin + PE. The JL version comes with compact box with Io-Link, Can-Open or analog interface and 5 pin M12 connection. The JH version has interface for fieldbus communication type PROFIBUS DP, EtherCAT, Ethernet/IP, Profinet, PowerLink or Can-Open, with 11 pin M12 connection.
