The FESE50CA-3X/1400LK0B1M throttle valve is produced by Bosch Rexroth and belongs to the FES Throttle Valves series for hydraulic automation. It converts an analog control signal into precise spool movement to manage flow. The command value input accepts 0 to 10 V so a typical PLC can drive the electronics directly. An actual value output of 0 to -10 V returns position feedback for closed-loop control. The electronics run on 21.6 to 36 V DC, tolerating supply variation on 24 V power buses. Maximum current consumption is 1.3 A, simplifying power supply selection. A duty cycle of 100 % allows continuous energization without cooling pauses. The IP65 housing protects against dust ingress and low-pressure water jets for field installation. The unit weighs 12.7 kg, which must be considered when designing mounting hardware.
The valve withstands a maximum operating pressure of 315 bar for use in high-pressure circuits. With a 10 bar differential, it passes up to 1400 L/min from port A to B, and the same 1400 L/min rating applies from B to A, giving equal performance in both directions. Minimum inlet pressures are 20 bar for A-to-B flow and 25 bar for B-to-A flow to keep the spool controllable. The pilot stage tolerates up to 315 bar, so it matches the main pressure class. Pilot oil demand reaches 12 L/min through port Y, a key value for sizing pilot lines. A full 0 % to 100 % command change displaces 23.4 cm³ of pilot oil, influencing response calculations. Together these hydraulic limits define reliable flow regulation in demanding applications.
