The DSE3J is a direct operated directional proportional valve, CETOP 03, with integrated electronics, feedback and mounting interface in compliance with ISO 4401 (CETOP RP 121H) standards.  The valve opening and hence flow rate can be modulated continuously in proportion to the reference signal.  Transducer and digital card allow a fine control of the positioning of the cursor, reducing hysteresis and response time and optimizing the performance of the valve.  It is available with fail safe function.  The valve is easy to install.  The driver directly manages digital settings.  For special applications, it’s possible to customize the settings using the optional kit.  The perfect combination for precise movements: the position feedback and the integrated electronics allow an hysteresis and repeatability lower than 0.2%, a frequency response that reaches the 50 Hz at <90° (with a 10% signal) and a pressure gain that allows to reach the 80% of total pressure with a 2% signal.  Possibility to use a mechanical zero overlap spool. In compliance with the EMC standards and IP67 protection degree. The optional kit LINPC-USB/10 enables the reading of the values coming from the external command, the exclusion of PLC and the direct control of the valve, the interfacing of PC and electronic card.

DSE3F

DIRECTIONAL CONTROL PROPORTIONAL VALVES WITH ELECTRICAL FEEDBACK
83240

The DSE3F is a direct operated directional proportional valve, CETOP 03, with feedback and mounting interface in compliance with ISO 4401 (CETOP RP 121H) standards.  It is normally used to control position and the speed of hydraulic actuators.  The valve opening and hence flow rate can be modulated continuously in proportion to the reference signal.  The valve must be controlled directly by the UEIK-*RSD digital card, that maximize the valve performances: the input signal and the signal from the valve are compared to obtain an accurate positioning and a reduces hysteresis.

The DSE5J is a direct operated directional proportional valve, CETOP 05, with integrated electronics (OBE - On Board Electronics), position feedback and mounting interface in compliance with ISO 4401 (CETOP RP 121H) standards.  It is normally used to control the direction and the speed of hydraulic actuators.  The valve opening and hence flow rate can be modulated continuously in proportion to the reference signal. Transducer and digital card allow a fine control of the positioning of the cursor, reducing hysteresis and response time and optimizing the performance of the valve.  The valve is easy to install. The driver directly manages digital settings. In the case of special applications, you can customize the settings using the optional kit.  This proportional valves are normally used to control the direction and the speed of hydraulic actuators. Transducer and digital card allow a reduced hysteresis and repeatability (lower than 0.2%), a response time of 60 Hz (at < 90° with a signal of 10%), and pressure gain that enables to reach the 80% of total pressure at 2% of reference signal.  The digital driver gives great performances, i.e. the response times reduction, the perfect interchangeability among different valves, the possibility to modify parameters via software. A spool with mechanical zero overlap is available, and the optional kit LINPC-USB/10 that enables the reading of the values coming from the external command, allows the exclusion of PLC to control the valve directly, and inteface PC and electronic card.
