The FES63CA-3X/1800LK4M throttle valve belongs to the FES Throttle Valves series and is produced by Bosch Rexroth for hydraulic automation where variable restriction of main flow and pilot functions are needed. It permits a maximum flow of 1800 L/min at a 10 bar differential, allowing the device to serve high-capacity manifolds. The main stage withstands operating pressures up to 315 bar, and the pilot stage can accept the same 315 bar through port X without functional change. Port Y handles pilot oil discharge up to 17 L/min, so auxiliary circuitry stays responsive during dynamic movements. Reliable actuation is maintained as long as inlet pressure at port A remains above 20 bar and pressure at port B stays above 25 bar. An orifice spool area ratio of 1.6:1 defines the throttling characteristic and hysteresis, while 52 cm³ of pilot oil is required to drive the spool through its full stroke.
Mounting and electrical details are arranged for straightforward integration. The pilot solenoid connects through a DIN EN 175301-803 plug, draws a nominal 1000 mA, and operates from a 24 V DC supply for direct interface with common machine control relays; this current keeps coil temperature moderate while generating consistent magnetic force. Mineral oil classified as HL or HLP according to DIN 51524 is the specified working fluid, which avoids varnish formation and maintains predictable viscosity under load. Installation into subplates or stacks follows the DIN ISO 7368 interface, secured by M30 × 100 bolts tightened to 1200 Nm to prevent fatigue at peak pressure; the bolt length matches the body thickness so clamping surfaces stay flush. The assembly weighs 21 kg, so two technicians or a lift assist may be needed when positioning the valve in compact power units.
