The Bosch Rexroth 4WRGE16V1-200L-1X/315G24TK31/A1M (R901058472) is a high-response directional valve known for its precision in controlling flow proportionally to the input signal. Engineered for subplate mounting, this valve is adept at managing flow continuously from P to B and A to T or from P to A and B to T. It features a low-friction pilot control valve with a dry gap torque motor, a housing with orifices and an integrated filter, as well as a spring-centered control spool within the main stage housing. The included control electronics come with an amplifier that controls both the pilot valve and the position of the main control spool, utilizing an inductive position transducer for accurate spool positioning.
This model offers various operational configurations such as external or internal pilot oil supply and drain options, denoted by type codes WRGEX, WRGEXE, WRGEXET, and WRGEXT. These configurations allow for flexibility in integrating the valve into different hydraulic systems. In case of power failure scenarios, it's important to note that certain safety behaviors are expected depending on the control spool form used.
The 4WRGE16V1-200L-1X/315G24TK31/A1M is suitable for applications requiring precise position, pressure, force, and velocity control under high dynamic requirements. Its design includes a single-stage servo pilot control valve operating on the nozzle-flapper plate principle and an inductive position transducer for main spool feedback. The unit boasts high response sensitivity with minimal hysteresis and features replaceable filter elements along with externally adjustable zero point correction capabilities.
For mounting specifications, it adheres to porting patterns according to DIN 24340 form A and ISO 4401 standards. This model has a maximum operating pressure of 315 bar and can handle nominal flows up to 200 l/min. Its component series X underscores its robustness within demanding hydraulic applications.

The 4/3 directional high-response valve is designed for subplate mounting, with position control and integrated control electronics. It controls the flow proportionally to the input signal, continuously from P to B and A to T or also from P to A and B to T.
Set-up:
The valve consists of four main assemblies:
low-friction pilot control valve (1) with dry 2-gap torque motor; valve housing (2) with orifices (3) and filter (4) Housing of the main stage (5) with spring-centered control spool (6) Control electronics (7) with amplifier to control the pilot control valve (1) and for the position control of the main control spool (6) inductive position transducer (8) for position sensing of the main control spool (6)
Functional description:
Control of the pilot control valve by means of a command value from 0 to ±10 V or from 0 to ± 10 mA Comparison command/actual value in the control electronics → In case of control deviation, the torque motor will be activated and the flapper plate will be deflected according to the control amplitude. Detuning of the control pressures using the control and fixed orifices → Deflection of the main control spool (6) Achievement of the position of the main control spool according to the command value presetting → Control deviation has been reduced to almost 0 V → Control process is completed Pilot oil supply to the pilot control valve internally via port P or externally via port X Pilot oil drain internally via port T or externally via Y to the tank
Notice:
In case of supply voltage failure, however with available operating pressure, the main control spool (6) will take an undefined position. The acceleration forces occurring in this connection may cause machine damage.
If a directional sandwich plate valve is used, the two control lines in the main stage will be short-circuited in case of power failure.
With control spool form E, E1- and Q2-, the centering spring (9, 10) bring the main control spool (6) in central position, V- and V1 control spools are switched to preferred direction P to B and A to T in a tolerance range of 1% to a maximum of 11% of the control spool stroke. In case of operating pressure failure and if no directional sandwich plate valve is used, you will observe the same behavior.
Type 4WRGE…-1X/…
Pilot oil supply external; pilot oil drain external
In this version, the pilot oil is supplied from a separate control circuit (externally).
The pilot oil drain is not directed into the T channel of the main valve, but is separately directed to the tank via port Y (externally).
Type 4WRGE…-1X/…E…
Pilot oil supply internal, pilot oil drain external
In this version, the pilot oil is supplied from the P channel of the main valve (internally).
The pilot oil drain is not directed into the T channel of the main valve, but is separately directed to the tank via port Y (externally). In the subplate, port X is to be closed.
Type 4WRGE…-1X/…ET…
Pilot oil supply internal, pilot oil drain internal
In this version, the pilot oil is supplied from the P channel of the main valve (internally).
The pilot oil is directly drained to channel T of the main valve (internally). In the subplate, ports X and Y are to be closed.
Type 4WRGE…-1X/…T…
Pilot oil supply external; pilot oil drain internal
In this version, the pilot oil is supplied from a separate control circuit (externally).
The pilot oil is directly drained to channel T of the main valve (internally). In the subplate, port Y is to be closed.
