VICKERS Proportional Valves Proportional Directional ...

1 Typical SectionKTG4V-5 General DescriptionVickers Proportional Valves shown inthis catalog are designed to provide acontrolled oil flow in proportion to acommand signal. They are available intwo types, firstly a double solenoidversion that will provide reversible flowand return to an actuator, andsecondly a single solenoid version thatprovides a single direction of are available for loadcompensation and if flowenhancement is required for the singlesolenoid version, parallel flow pathmodules are available that will boostthe flow capacity to nearly twice that ofthe standard , both of these valve typescan be supplied with or without anintegral amplifier built directly onto version is supplied without theintegral and BenefitsDWide range of spool and flow rateoptionsDSupported by amplifiers andauxiliary function modules from theVickers rangeDElectronic feedback LVDT ensuresaccurate speed controlDCurrent feedback provides inherentprotection from electricalinterferenceDVibration and shock testedKAD/TG4V-5 KAD/TG4V-5A range of Proportional Directional andthrottle Valves with control amplifiers builtdirectly on, and prewired to, the adjustments of gain, spooldeadband compensation, dither andoffset ensure high only electrical inputs required arepower supply (24V) and a voltagecommand signal of "10V.

The screen of the cable must be securely connected to the shell of the metal connector. Asuitable IP67 rated connector is available from VICKERS , part no. 934939. This must be tightened with a torque of2-2,5 Nm ( lbf-ft) to achieve the IP67 rating.
