The FE16C-2X/50LK4M throttle valve belongs to the FES Throttle Valves series from Bosch Rexroth and meters oil flow in hydraulic automation. Its size 16 housing slips into DIN ISO 7368-BA-06-2-A cavities, so machine builders can swap cartridges without machining new blocks. The direction of flow is from port A to port B, clarifying how line connections must be arranged. A linear flow characteristic provides proportional opening, enabling predictable speed control when the spool is driven incrementally. With a 10 bar differential pressure the valve passes up to 190 L/min, giving adequate capacity for medium-size actuators. The assembly withstands a maximum operating pressure of 315 bar, permitting use on high-pressure pump lines. A minimum inlet pressure of 7 bar from A to B is required to start throttling action, and only 0.9 cm³ of pilot oil is displaced from 0 to 100 percent stroke, which supports fast response in closed-loop systems.
The solenoid stage is rated at 24 V DC, letting the valve draw power directly from common control supplies, and it requires a nominal current of 1000 mA to reach full travel. Coil resistance is 12.7 Ω at 20 °C, a value that keeps heat generation within limits during continuous duty. A 100 percent duty cycle confirms the coil may remain energized indefinitely without thermal cycling. Electrical termination is through a DIN EN 175301-803 connector, so wiring harnesses can follow standardized pin layouts. When the matching cable socket is fitted the enclosure achieves an IP65 rating, protecting the coil against dust and water jets found near presses or test stands. NBR seals isolate the internal flow path from the environment and suit mineral-oil based fluids. Total weight is 2.7 kg, light enough for overhead manifold mounting without additional supports.
