Product description

Set-up

The pilot-operated directional high-response cartridge valve type 2WRC. basically consists of:

• Cover (1)

• Control spool (2)

• Socket (3)

• Position transducer (4)

• Integrated electronics (5)

• Damping plate (6)

• Pilot control valve (7)

• Ethernet IN (X7E1); Ethernet OUT (X7E2)

• Connector, voltage supply (XH1)

Function

The integrated electronics (5) compares command and actual values and actuates the solenoid of the pilot control valve with a proportional current according to the control deviation.

The pilot control valve (7) takes a proportionally controlled position and controls the flows that actuate the control spool (2) through the closed valve control loop up to zero control deviation.

This means that the stroke of the control spool (2) is regulated proportionally to the command value. It must be noted that the flow also depends on the valve pressure drop.

Valve features

The flow can pass through the valve from A to B or from B to A. The control spool (2) closes or opens at 5 % of the command value. At lower command values, the valve control loop attempts to guide the control spool (2), thus presses it onto the seat at full pilot pressure and blocks the connection in a leakage-free way. The specified valve dynamics only apply to the control area of the valve.

At command value steps from the seat to lower opening values, additional delay times occur.

The opening point of 5 % (= 0.5 V or 4.8 mA) is set at the factory. The pilot control valve (7) is designed as bi-directionally controlled longitudinal spool valve with double stroke solenoid and control sleeve and has a mechanical trimming in case of power failure. The integrated electronics (5) regulates the position of the control spools of main and pilot control stage and offers either the analog interfaces “A1” and “F1” or the full bus functionality with interface “D9”.

Damping plate "D"

The damping plate (6) reduces the acceleration amplitudes on the on-board electronics (frequencies >300 Hz).

Notice:

Use of the damping plate is not recommended for applications with mainly low-frequency excitation <300 Hz.

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. Bio-degradable and flame-resistant – containing water: If components with galvanic zinc coating (e.g. version "J3" or "J5") or parts containing zinc are used, small amounts of dissolved zinc may get into the hydraulic system and cause accelerated aging of the hydraulic fluid. Zinc soap may form as a chemical reaction product, which may clog filters, nozzles and solenoid valves - particularly in connection with local heat input. 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.

Notices:

• Do not connect PE if the valve has already been grounded via the system.

• In case of cable break, valves of version "K" are - according to the factory setting - regulated and by default held in a closed position. Valves of version "L" are by default held in an open position. On the customer side, a so-called standstill value can be defined in IndraWorks DS by changing the parameters.

Project planning information

Project planning and maintenance instructions

• The supply voltage must be permanently connected, as otherwise bus communication is not possible.

• If electro-magnetic interference is to be anticipated, suitable measures must be taken to ensure the function (depending on the application, e.g. shielding, filtration).

• The devices have been tested in the plant and are supplied with default settings.

• Only complete devices can be repaired. Repaired devices are returned with default settings. User-specific settings will not be applied. The machine end-user will have to retransfer the corresponding user parameters.
