Description Size 10 … 27 Component series 4X Maximum operating pressure 350 bar Maximum flow 1850 l/min Nominal flow 60 … 600 l/min Features Open - Integrated fieldbus (IFB Multi-Ethernet) - Bus connection/service interface (Sercos, EtherCAT, EtherNet/IP, PROFINET RT, POWERLINK, VARAN) Scalable - 2 configurable analog pressure sensor inputs Precise - Integrated pressure-force control - High response sensitivity and little hysteresis Safe - Internal safety function (can be used up to category 4/PL e according to EN13849-1) - CE conformity according to EMC Directive 2014/30/EU 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.
