2 X Y X RA 9 /6.98 Functional description The Model FE..C -way electronic proportional cartridge valve is an adjustable orifice, the opening stroke of which is preset by means of an electronic input signal to the proportional solenoid. The valve is supplied as a unit ready to install, in a standard logic cavity. In the cover () is the sleeve () with the main spool (5), the positional transducer (), the pilot control (8) and the proportional solenoid (9). The direction of flow is from A to B. The pilot fluid connection X is connected to port A. The pilot fluid drain Y should be led back to tank at minimum pressure. A comparison between the external input signal and the actual value signal (feedback from the positional transducer) is made within the amplifier (). The current to the proportional solenoid (9) is then altered to correspond to the differential value. The proportional solenoid (9) converts the electrical positional signal into movement of the pilot control (8) The pressure in the spring chamber (7) is then adjusted so that the spring-loaded main spool (5) moves into a position corresponding to the input signal value. Should the solenoid current or the feedback signal fail, the orifice closes automatically (safety control). The internal circuitry of the positional control are arranged so that the input value and the stroke of the spool (5) are directly proportional to each other. For a given pressure drop across the orifice, the volumetric flow from A to B is only dependent on the spool position and the window geometry (6). Direct proportionality is achieved between in-put value and output flow, with linear window geometry (FE..C/L..). Model FE..C/ Q.. has an orifice design which provides a progressive relationship between input value and flow. Electronic amplifier card Model VT 5... VT 56 (dependent on valve size) must be ordered separately, see RA Signal value 9 8 B B Model FE..C X/.. (Size to 6) A Model FE..C X/.. (Size 6, 5) A /
