The FESE40CA-3X/670LKOG1M throttle valve belongs to the FES Throttle Valves series and is manufactured by Bosch Rexroth for proportional flow control in hydraulic automation. It operates on a DC supply from 21.6 V to 36 V so power sources within that range can drive the actuator coil. Continuous service is possible because the duty cycle is 100 percent, while the coil draws a steady 1.3 A and can accept pulse loads up to 1.5 A during switching. Each actuation needs 12 cm³ of pilot oil, helping keep response time short. An IP65 enclosure shields internal components from dust and water, and the assembly weighs 8.4 kg for manageable manifold installation.
At a differential pressure of 10 bar the valve passes a nominal 670 L/min, reaching 680 L/min when flow is from port a to b and 585 L/min when the direction is reversed. Reliable function requires at least 15 bar inlet pressure in the a-to-b direction or 20 bar from b-to-a. The main stage tolerates operating pressures up to 315 bar, and the pilot stage is built for the same 315 bar limit while drawing no more than 10 L/min through port Y. These values allow the unit to meter large flows accurately in high-pressure circuits without exceeding its structural or pilot capacities.
