The Bosch Rexroth 3WRCE50V000X-2X/SG24K31/C5M-140 (R901212336) is a high-response directional valve designed for precise control of flow and direction within hydraulic systems. This valve is particularly suitable for applications requiring exacting control such as in presses, die casting machines, and nibbling axes. It features an advanced three-stage setup that includes a stage pilot control valve with a dry torque motor, a low-friction nozzle flapper plate amplifier, and mechanical feedback of the spool position. Additionally, it incorporates a main stage for flow control and an inductive position transducer.
The core function of this valve is to compare command values with actual values, adjusting the torque motor of the pilot control valve proportionally to correct any deviation. The result is precise regulation of the main spool's stroke proportional to the input command value. It's important to note that flow is also dependent on the pressure drop across the valve.
One unique aspect of this Bosch Rexroth valve is its factory-set opening point for the V spool. However, after replacing either the pilot control valve or control electronics, users can adjust this setting using the zero adjustment potentiometer R. In terms of maintenance, only the filter element may need to be exchanged without affecting other settings.
This model boasts integrated electronics OBE and offers reliability in operation with features like compensation for pilot trimming and a mechanism that opens from A to T in case of power failure when pilot pressure is applied. The spring behind the main spool ensures that P to A is closed if no pressure is applied.
The 3WRCE50V000X-2X/SG24K31/C5M-140 operates with a maximum pressure of up to bar and can handle maximum flow rates of l/min. This high-response valve demonstrates Bosch Rexroth's commitment to providing robust solutions for sophisticated hydraulic control tasks.

Valves of type 3WRCE are 3-stage high-response valves. They control the quantity and direction of a flow and are mainly used in control loops.
Set-up
They consist of the following assemblies:
2-stage pilot control valve (1) with dry torque motor low-friction nozzle flapper plate amplifier and mechanical feedback of the spool position a main stage (2) for flow control an inductive position transducer (3) the core (4) of which is attached to the spool (5) of the third stage and integrated control electronics (6).
Function
The integrated or external electronics compares command and actual values and the torque motor of the pilot control valve is actuated with a proportional current according to the control deviation.
The pilot control valve takes a proportionally controlled position and controls the flow in and out of the control chambers A (7) and B (8) that actuate the main spool (5) through the closed valve control loop up to 0 control deviation.
This means that the stroke of the main spool is regulated proportionally to the command value. It must be noted that the flow also depends on the valve pressure drop.
Valve particularities
The opening point of 0 % (V spool) is set at the factory. Upon replacement of the pilot control valve or the control electronics, the opening point can be readjusted using the zero adjustment potentiometer R316, accessible via a plug screw.
During the exchange, no settings must be made at the control electronics (= controller or control electronics) and the pilot control valve, except for the zero adjustment at the position transducer.
At the pilot control valve, only the filter element may be exchanged (see “directional servo valves”)
The pilot control valve is trimmed so that the pilot pressure is connected to control chamber B (8) in case of a power failure, i.e. the main stage is opened from A to T or the connection P to A is closed.
The spring behind the main spool moves it into position so that P to A is closed if no pressure is applied (e.g. prior to installation, before the pressures are reapplied after tool change).
The control electronics feature an offset to compensate the trimming of the pilot control valve (pilot trimming).

Nominal command value range for 3WRCE:
0 ... ±10 V (mA) ≙ 0 ... ±100 %
With a slow command value change from 0 V to ±10 V, the actual value follows the command value within ±0.1 V.
With command value greater than ±10 V, then the actual value can briefly reach values of approx. ±10.5 V.
