The FE16C-2X/140LK4M throttle valve is part of the FES Throttle Valves series manufactured by Bosch Rexroth for precise hydraulic automation. It is energized at a nominal voltage of 24 V DC and requires a nominal current of 1000 mA to position the spool. A coil resistance of 12.7 Ω measured at 20 °C supports this current draw, while a 100 % duty cycle allows continuous actuation without overheating. Magnetic force is modulated at an oscillator frequency of 2.5 kHz to achieve stable throttling across the control range. Electrical hookup is provided through a DIN EN 175301-803 connector, and the housing carries an IP65 rating to block dust and water spray. Fluid is retained by NBR seals, and the assembled unit weighs 2.7 kg for straightforward manifold installation.
The valve delivers a nominal flow of 140 L/min at a pressure drop of 10 bar and can pass up to 190 L/min in the same conditions when additional capacity is needed. Ports a and b tolerate operating pressures up to 315 bar, matching the maximum pilot pressure applied at port x, while pilot oil flow at port Y is limited to 2.5 L/min to minimize control losses. The inlet side must reach at least 7 bar before flow begins to move from a to b, and a stroke from 0 % to 100 % displaces 0.9 cm³ of pilot oil. These hydraulic figures define the response window and ensure accurate throttling within high-pressure circuits.
