The FE16C-2X/100LK4M throttle valve belongs to the FES Throttle Valves series from Bosch Rexroth and meters flow in hydraulic automation circuits. Its size 16 housing supplies an orifice area sized for medium-capacity manifolds without excessive pressure drop. A nominal flow of 100 L/min at Δp = 10 bar defines the maximum throughput while maintaining controllable throttling. Flow is allowed only from port A to port B, simplifying line routing and preventing reverse leakage. The spool remains stable because a minimum inlet pressure of 7 bar is required before modulation begins. System pressures up to 315 bar can be applied, letting the valve operate in high-pressure power units. Mineral oil classified as HL or HLP under DIN 51524 is the approved hydraulic medium, and NBR seals are fitted to resist swelling in that fluid. The complete assembly weighs 2.7 kg, so it can be handled easily during manifold installation.
The solenoid actuator uses a 24 V DC supply and draws a nominal current of 1000 mA to position the throttling element proportionally. Coil resistance is 12.7 Ω at 20 °C, matching the voltage-current pairing to limit heating under continuous duty. A DIN EN 175301-803 connector forms the electrical interface and, when mated, enables an IP65 protection class that keeps dust and low-pressure water from reaching the coil. Pilot control stages can accept pressures up to 315 bar, and full command travel displaces only 0.9 cm³ of pilot oil to reduce response lag. During operation the pilot line flow through port Y peaks at 2.5 L/min, limiting auxiliary pump demand. These characteristics support precise throttle control in closed-loop systems while providing straightforward electrical integration and robust environmental sealing.
