Product description

Valves of type 4WRDE are 3-stage, pilot-operated directional control valves with electrical position feedback and integrated electronics (OBE).

Set-up

The valves basically comprise of:

Servo pilot control valve, 2-stage, type 4WS2EM6-2X (1)

Main stage (2), consisting of housing and main stage control spool

Integrated electronics (3) with inductive position transducer of the main stage

Function

In the integrated electronics (OBE), the specified command value is compared with the position actual value of the main stage control spool. In case of a difference (control deviation), the first stage of the pilot control valve is controlled (dry torque motor and nozzle flapper plate system). This way, a deflection of the flapper plate of the nozzle flapper plate system is realized. The distance of the flapper plate to one of the two control nozzles flown-through by pilot oil is reduced and increased to the other one. Through the connecting bore, the resulting flow difference leads to deflection of the control spool in the pilot control valve (2nd stage) similarly to the control signal. The flow released by the pilot control valve leads to deflection of the control spool of the main stage (3rd stage) until its position actual value corresponds to the command value. The stroke of the control spool is controlled proportionally to the command value.

Valve features

The valves are factory-set with a dither default setting with the constant frequency of 400 Hz.

Failure of supply voltage

With applied pilot oil pressure, the main stage control spool moves into an undefined end position. The acceleration forces occurring in this connection may cause machine damage.

If a directional sandwich plate valve is used (see ordering code), the two pilot oil chambers in the main stage will be short-circuited in case of power failure.
- With symbol E, E1-, W6 and W8, the main stage spool will take the spring-centered central position.
- With symbol V and V1, the main stage spool takes the offset position, operated by the spring (P–B and A–T) (in the tolerance range 1 ... 11% of the control spool stroke)

Notes:

Changes in the zero point and/or the dither amplitude may result in damage to the system and may only be implemented by instructed specialists.

The pilot control valve may only be maintained by Rexroth employees. An exception is the replacement of the filter and the sealing according to accessories list. It has to be ensured that during the assembly, the sealing is properly seated and the plug screw is tightened. The tightening torque for the plug screw is 30 Nm

Important information on hydraulic fluids: For more information and data on the use of other hydraulicfluids, please refer to the data sheets above or contact us. There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum surface temperature. Flame-resistant – containing water: Due to increased cavitation tendency with HFC hydraulic fluids, the life cycle of the component may be reduced by up to 30% as compared to the use with mineral oil HLP. In order to reduce the cavitation effect, it is recommended - if possible specific to the installation - to back up the return flow pressure in ports T to approx. 20% of the pressure differential at the component. Dependent on the hydraulic fluid used, the maximum ambient and hydraulic fluid temperature must not exceed 50 °C. In order to reduce the heat input into the component, the command value profile is to be adjusted for proportional and high-response valves.

1)	At active hydraulic pressure and "low" enable signal, the control spool of the main stage is in a regulated central position (preferred direction adjustable by ±10% by means of potentiometer R161). If a directional sandwich plate valve (version "WG") is used between pilot control valve and main stage, the control chambers are unloaded from the pilot control valve to the main stage control spool. With symbols E, E1-, W6- and W8-, the centering springs set the main stage control spool in central position, symbols V- and V1 are switched to preferred direction P → B and A → T in a tolerance range of 1% to 11% of the control spool stroke. As a consequence, the cylinder axis leaves its position at minimum velocity.
2)	Differential command value input: Positive command value at D compared to E results in flow from P → A and B → T at the main stage.
3)	Differential command value input: Command value of 12 … 20 mA at D compared to E results in flow from P → A and B → T at the main stage.
