The FESE25CA3X/315LKOG1M is a throttle valve produced by Bosch Rexroth within the FES Throttle Valves series. It modulates hydraulic flow in automated machinery so that actuators receive controlled pressure and volume. The unit is powered by a 24 V DC supply, and its current consumption of 1.3 A keeps electrical load on the control cabinet low. A 100 % duty cycle allows the coil to remain energized continuously without cooling pauses, supporting constant regulation. Connection is made through a DIN 43651 plug, simplifying wiring with standard industrial connectors. The valve tolerates ambient temperatures up to 50 °C, while a maximum hydraulic fluid temperature of 80 °C protects internal components from thermal degradation. An NBR seal limits external leakage and resists common mineral oils, and the 4 kg mass enables installation by a single technician.
Flow capacity and pressure ratings define how the FESE25CA3X/315LKOG1M behaves once installed. The assembly withstands operating pressures of 315 bar at ports A and B, and the same 315 bar is permitted at pilot port X, so it can be incorporated in high-pressure circuits. Minimum inlet pressures are 12 bar for flow from A to B and 15 bar for the reverse direction, ensuring the throttling element opens predictably. Under a 10 bar differential, nominal flow reaches 315 l/min, while the channel from A to B can pass up to 360 l/min when higher demand occurs. Pilot control uses at most 5.0 l/min through port Y, and moving the slide from closed to fully open displaces 3.9 cm³ of pilot oil, data that assists in sizing the pilot line and response time. Together these figures let designers match the valve to cylinder speeds and system pressure limits.
