CONTINENTAL c: HYDRAULICS VED03MX - HIGH PERFORMANCE, SERVO-PROPORTIONAL DIRECTIONAL CONTROL VALVE ELECTRICAL CHARACTERISTICS The proportional valve is controlled by a digital amplifier (driver), which incorporates a microprocessor that controls all the valve functions. THE STANDARD VALVE IS SET AT THE FACTORY WITH: - UP/DOWN ramp at zero value - Max valve opening (100% of spool stroke) It is possible to customize these and others parameters using the optional kit, VEA-PB7 to be ordered separately (see related literature). THE DIGITAL DRIVER ENABLES THE VALVE TO REACH BETTER...

E0 VERSION - VOLTAGE REFERENCE SIGNAL Reference signal required is ± 10 volt. The monitor signal is ± 10 volt. This signal is available 0.5 sec after card is powered on OBW / OBM. VED03MX - HIGH PERFORMANCE, SERVO-PROPORTIONAL DIRECTIONAL CONTROL VALVE E1 VERSION - CURRENT REFERENCE SIGNAL Reference signal required is 4-20 mA. If the current value drops below 4 mA, the card will shut down until the correct signal has been applied. The monitor signal is 4-20 mA. This signal is available 0.5 sec after card is powered on OBW / OBM. SALES@CONTHYD.COM - WWW.CONTINENTALHYDRAULICS.COM

VED03MX - HIGH PERFORMANCE, SERVO-PROPORTIONAL DIRECTIONAL CONTROL VALVE OBC / OBW / OBM VERSIONS OBC version is programmed for use of an external 24 volt Enable signal applied at Pin C to allow the valve to function. The Monitor signal output is referenced between Pin F and Pin B. OBW version is programmed for Internal enable, power for enable is taken directly from the power supply. The power to the valve must be turned off to disable the valve. The Monitor signal output is referenced between Pin F and Pin B. OBM version is programmed for Internal enable, power for enable is taken...

CONTINENTAL c HYDRAULICS APPLICATION DATA FLUIDS All pressure drops shown on these data pages are based on 170 SUS fluid viscosity and 0.87 specific gravity. For any other specific gravity (G1) the pressure drop (AP) will be approx. API = AP (G1/G). See the chart for other viscosities. FLUID VISCOSITIES Use mineral oil-based hydraulic fluids HL or HM type, according to ISO 6743-4. For these fluids, use NBR seals. For fluids HFDR type (phosphate esters) use FPM seals (code G). For the use of other kinds of fluid such as HFA, HFB, HFC, please consult our technical department. Using fluids at...
