The FESE25CA-3X/315LK0B1M-1 throttle valve belongs to the FES Throttle Valves series and is manufactured by Bosch Rexroth for proportional flow control in hydraulic automation circuits. It is built in size 25, giving a nominal flow of 315 L/min at a 10 bar pressure drop so the main stage can sustain constant volume under typical load. During transient peaks, the valve can pass up to 360 L/min from port A to B with the same differential, preventing pressure spikes. A maximum operating pressure of 315 bar allows installation in high-pressure lines, while a minimum inlet pressure of 12 bar in the A-to-B direction and 15 bar in the B-to-A direction guarantees reliable opening in either flow path. The pilot stage needs only 3.9 cm³ of oil per shift, reducing control energy, and accepts a pilot pressure up to 315 bar so the actuator remains responsive even in demanding systems.
Continuous duty is supported by a 100 percent duty cycle and an electrical supply window from 21.6 V to 36 V; at 36 V the coil draws no more than 1.3 A, keeping heat generation low in enclosed manifolds. The valve connects through a DIN 43651 plug, simplifying field wiring, and the enclosure carries an IP65 protection rating to block dust ingress and water jets in mobile or factory settings. Maximum pilot oil flow through port Y is limited to 5.0 L/min, which stabilizes spool movement and prevents control overshoot. Overall weight is 4 kg, light enough for mounting directly on subplates without auxiliary supports. A pilot pressure ceiling of 315 bar aligns with the main stage strength, ensuring uniform stress margins. These electrical, hydraulic, and mechanical parameters together define the valve’s role as a precise, reliable throttling element in automated hydraulic platforms.
