The Bosch Rexroth 2WRCE63K001-1X/PG24/M-66 (R900733105) is a highly sophisticated stage high response valve designed to precisely control the rate and direction of flow in closed loop control circuits. This product incorporates a series of advanced subassemblies including a pilot control valve with a servo directional valve pilot, a dry torque motor, a low friction jet flapper amplifier, and mechanical feedback for spool position. Additionally, it features an inductive position transducer linked to the main control spool and integrated control electronics for precise operation. The functionality of this valve is centered around its ability to compare command and actual values within the integrated electronics OBE, adjusting the pilot control valve solenoids accordingly to minimize system deviation. Its design allows for fluid flow in both directions from A to B or B to A, with leak-free closure at low command values due to the spool being pressed onto its seat by full system pressure. This valve is particularly notable for its block installation design, external or integrated control electronics depending on the device type, and its capability for closed-loop or open-loop control of large flows. It's an ideal component for applications requiring high precision and responsiveness such as in forging manipulators, pressing cylinders, and die casting machines. Moreover, the 2WRCE63K001-1X/PG24/M-66 ensures reliable performance with features like factory preset opening points that can be calibrated post-replacement. However, users must be aware that certain conditions such as power loss at the pilot control valve can leave the spool in an undefined position. For optimal function and safety, it's recommended that port B connects directly to the actuator. This Bosch Rexroth product demonstrates a commitment to quality and precision in hydraulic system components.
The valve types 2WRC(E) are 3-stage high response valves.
They control the rate and direction of a flow and are primarily used in closed loop control circuits.
Design
They comprise of the following sub-assemblies:
A pilot control valve (1) as a 2-stage servo directional valve (pilot) With a dry torque motor Low friction jet / flapper amplifier and Mechanical feedback of the spool position A main control spool (2) for flow control An inductive position transducer (3) whose core (4) is attached to the spool (2) of the third stage And integrated control electronics (5) for 2WRCE orseparate electronics for the 2WRC version.Function
Within the integrated control electronics (OBE) the command and actual values are compared and the pilot control valve solenoids are controlled via a currrent proportional the closed loop control deviation.
The pilot control valve asumes a proportional control position and controls the flows into or from control chambers A (6) and B (7), that actuate the main spool (2) by means of the closed loop control valve until the system deviation is 0.
The stroke of the main spool is thus controlled in proportion to the command value. It must be noted herethat the flow also depends on the valve pressure drop.
Valve features
Flow can be passed through the valve from A to B or from B to A.
The poppet spool closes or opens with a command value of approx. 2 %. With smaller command values the valve‘s closed loop control circuit trys to correct the spool position and thereby presses the spool, with up to the full system pressure, onto its seat and closes the connection leak-free.
The stated switching times are only valid for the closed loop control range of the valve. With command value jumps from the seat to small opening values, additional delay times occur.
The 2 % opening point (= 0.2 V) is factory pre-set. When replacing the pilot control valve or control electronics the opening point can be calibrated by adjusting the position transducer (3) by using the 13A/F nut.
When carrying out an exchange no adjustments to the control electronics and pilot control valve (= closed loop controller, controller or control electronics), other than the zero calibration at the position controller may be carried out.
Only the filter element can be replaced on the pilot control valve (see data sheet „Servo directional valve“)
Due to the diameter differences in the seat area, the spools are not pressure balanced. To compensate for the force differences for spool „K001“ 6 %, and for spools „D001“ and „S001“ 22 % of the system pressure is required as the control pressure, and then by adding reserves for flow forces and dynamics, the recommended minimum control pressure can be obtained (see technical data).
Attention:
A loss of power at the pilot control valve results in the spool being in an undefined position (2).

Nominal command value range for 2WRCE:
0 ... +10 V ≙ 0 ... 100 %
In the command value range of 0 ... 0.2 V, the actual value remains constant at 0.2 V.
In case of slow command value modification from 0.2 V ... 10 V, the actual value follows the command value within ±0.1 V.
At a command value step to 10 V, the actual value can reach short-time values of up to approx. 10.5 V.
measured with HLP32, ϑOil = 40±5 °C
A Δp = 5 bar relates to a 100% flow value of the nominal flow of the associated table.
