Product description

General information

The pilot-operated IFB Multi-Ethernet valve (Integrated Fieldbbus) is a digital directional control valve with integrated fieldbus:

  • The following operating modes are possible:
  • Standard:
    • Valve direct control
    • Flow control
  • Version "5" (with external pressure sensors):
    • Pressure/force control
    • Active damping
    • Substitutional control (flow - pressure/force); pQ function (flow-controlled)

  • Command value presetting is done via the Ethernet interface (X7E1 or X7E2)
  • The feedback information of the actual value signals to the superior control system is provided via the Ethernet interface (X7E1 or X7E2)
  • The controller parameters are set via the Ethernet interface (X7E1 or X7E2)

Set-up

The directional control valve with IFB Multi-Ethernet electronics mainly consists of:

  • Pilot control valve (1) with control spool and sleeve in servo quality
  • Main stage (2) with centering springs and position feedback
  • Integrated fieldbus (3) with:
    • connector, voltage supply, safety shut-down (XH1)
    • Ethernet interfaces (X7E1, X7E2)
    • analog sensor interfaces (X2N)
    • interface for the position transducer of the main stage (X8A)
1)Only version "5"

Function (symbol V, V1- and Q3-)

When the control solenoid of the pilot control valve is de-energized, its spring-operated control spool is in the "fail safe" position. The control spool of the main valve is in the spring-centered offset position at approx. 6% of the stroke in direction P→B/A→T.

The integrated electronics (OBE) compare the specified command value to the position actual value of the control spool of the main stage. In case of a control deviation, the control solenoid of the pilot control valve is activated and its control spool is adjusted.

The flow which is activated via the control cross-sections at the pilot control valve leads to an adjustment of the control spool of the main valve. The stroke/control cross-section of the main valve is regulated proportionally to the command value. In case of a command value presetting of 0%, the electronics adjust the control spool of the main valve to central position.

The pilot oil supply in the pilot control valve is either internal via port P or external via port X. The feedback can be internal via port T or external via port Y to the tank.

Switching off the release (symbol V and V1-)

The control spool of the main valve is not in a safe position after the release is switched off. The enable acknowledgement is not set (pin C). If the supply voltage fails or in case of cable break, the integrated electronics will de-energize the control solenoid, the pilot control spool will move to the fail-safe position and will unload the pilot oil chambers of the main valve. Operated by the spring, the control spool of the main valve will move to the offset position (approx. 6% P→B/A→T).

Function (symbol E. and W.)

When the control solenoid of the pilot control valve is de-energized, its spring-operated control spool is in the "fail safe" position. The control spool of the main valve is in spring-centered central position.

The integrated electronics (OBE) compare the specified command value to the position actual value of the control spool of the main stage. In case of a control deviation, the control solenoid of the pilot control valve is activated and its control spool is adjusted.

The flow which is activated via the control cross-sections at the pilot control valve leads to an adjustment of the control spool of the main valve. The stroke/control cross-section of the main valve is regulated proportionally to the command value.

The pilot oil supply in the pilot control valve is either internal via port P or external via port X. The feedback can be internal via port T or external via port Y to the tank.

Switching off the release (symbol E., W. and Q3-)

If the control spool of the main valve is in the safe position, the enable acknowledgement is set (pin C).

If the control spool of the main valve leaves the safe position or the release is set, the enable acknowledgement expires. If the supply voltage fails or in case of cable break, the integrated electronics will de-energize the control solenoid, the pilot control spool will move to the fail-safe position and will unload the pilot oil chambers of the main valve. Operated by the spring, the control spool

of the main valve will move to the central position.

Monitoring

The digital control electronics enable comprehensive monitoring functions/error detection including:

  • Undervoltage
  • Communication error
  • Cable break for analog sensor inputs
  • Monitoring of the microcontroller (watchdog)
  • Temperature of the integrated electronics

IndraWorks DS PC program

To implement the project planning task and to parameterize the valves, the user may use the IndraWorks DS engineering tool (see accessories):

  • Project planning
  • Parameterization
  • Commissioning
  • Diagnosis
  • Comfortable administration of all data on a PC
  • PC operating systems: Windows 7-10

Notice:

  • Symbol V and V1-:
    • Pilot-operated 4/3 directional control valves are only functional in the active control loop and do not have a locking basic position when deactivated. Consequently "external isolator valves" are required in many applications and must be taken into account regarding the switch-on/switch-off order.
    • While the electrical supply voltage is being switched off, the drive may be accelerated for a short time in functional direction P → B.
  • Symbol E. and W.:
    • Pilot-operated 4/3 directional control valves with positive overlap are functional in controlled or regulated axes. The overlap in the de-energized state is approx. 20% of the control spool stroke.
    • While the release is being switched off, the drive may be accelerated for a short time in functional direction P → B (see operating instructions 29391-B).

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.

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.
